101-551: The River Mun or Mundesley Beck is a river in the north of the county of Norfolk , England. Its source is in the parish of Northrepps . The river finally runs into the North Sea in the village of Mundesley . The river's source is next to Craft Lane, close to Furyhill plantation between Northrepps and the hamlet of Frogshall . It runs in a southeasterly direction through a wooded valley and passes under Craft Lane close to Frogshall Farm House. From here it runs through woodland for

202-517: A Gross Domestic Product of £ 9,319 million, which represents 1.5% of England's economy and 1.25% of the United Kingdom's economy. The GDP per head was £11,825, compared to £13,635 for East Anglia, £12,845 for England and £12,438 for the United Kingdom. In 1999–2000 the county had an unemployment rate of 5.6%, compared to 5.8% for England and 6.0% for the UK. Data from 2017 provided a useful update on

303-567: A saffron grower. Over 20% of employment in the county is in the agricultural and food industries. Well-known companies in Norfolk are Aviva (formerly Norwich Union ), Colman's (part of Unilever ), Lotus Cars and Bernard Matthews Farms . The Construction Industry Training Board is based on the former airfield of RAF Bircham Newton . Brewer Greene King, food producer Cranswick and feed supplier ForFarmers  [ nl ] were seeing growth in 2016–2017. A local enterprise partnership

404-403: A Norfolk pantiled roof. Seen from the roadside, Mundesley Mill has five floors but if you took the public pathway round to the back, only two would have been visible. This is because the mill pool lying behind was level with the third floor. The builders set the mill deep into a high bank, over which the water would have fallen freely in the old days before findings its way to the beach, although it

505-597: A fifth generation crabman, who sells Cromer Crabs to eateries such as M Restaurants and the Blueprint Café. The problem that he has found is attracting young people to this small industry which calls for working many hours per week during the season. Lobster trapping also continued in North Norfolk, around Sheringham and Cromer , for example. Norfolk's low-lying land and easily eroded cliffs, many of which are composed of chalk and clay, make it vulnerable to weathering by

606-399: A large head compared to other types of wheel which usually means significant investment in constructing the headrace. Sometimes the final approach of the water to the wheel is along a flume or penstock , which can be lengthy. A backshot wheel (also called pitchback ) is a variety of overshot wheel where the water is introduced just before the summit of the wheel. In many situations, it has

707-597: A large scale. By the 5th century the Angles had established control of the region and later became the "north folk" and the "south folk"; hence "Norfolk" and " Suffolk ". Norfolk, Suffolk and several adjacent areas became the kingdom of East Anglia (one of the heptarchy ), which later merged with Mercia and then with Wessex . The influence of the early English settlers can be seen in the many place names ending in "-ham", "-ingham" and "-ton". Endings such as "-by" and "-thorpe" are also fairly common, indicating Danish toponyms: in

808-454: A major change of the river. Their disadvantages are their low efficiency, which means that they generate less power and can only be used where the flow rate is sufficient. A typical flat board undershot wheel uses about 20 percent of the energy in the flow of water striking the wheel as measured by English civil engineer John Smeaton in the 18th century. More modern wheels have higher efficiencies. Stream wheels gain little or no advantage from

909-441: A moderate head . Undershot and stream wheel use large flows at little or no head. There is often an associated millpond , a reservoir for storing water and hence energy until it is needed. Larger heads store more gravitational potential energy for the same amount of water so the reservoirs for overshot and backshot wheels tend to be smaller than for breast shot wheels. Overshot and pitchback water wheels are suitable where there

1010-544: A poem by Antipater of Thessalonica , which praises it as a labour-saving device (IX, 418.4–6). The motif is also taken up by Lucretius (ca. 99–55 BC) who likens the rotation of the waterwheel to the motion of the stars on the firmament (V 516). The third horizontal-axled type, the breastshot waterwheel, comes into archaeological evidence by the late 2nd century AD context in central Gaul . Most excavated Roman watermills were equipped with one of these wheels which, although more complex to construct, were much more efficient than

1111-449: A reversible water wheel was by Georgius Agricola and dates to 1556. As in all machinery, rotary motion is more efficient in water-raising devices than oscillating motion. In terms of power source, waterwheels can be turned by either human respectively animal force or by the water current itself. Waterwheels come in two basic designs, either equipped with a vertical or a horizontal axle. The latter type can be subdivided, depending on where

1212-677: A short distance and into a large pool called Little Broad. From Little Broad, still in woodland, the river falls over a weir and into marshy woodland known as Osier Carr, where freshwater mussels can be found. The river then passes under another lane from Sidestrand . From here the river feeds ponds and sluices in an area known as the Grove. Many drains feed into the river here. The river then turns almost south and passes under Cromer Road, then crosses countryside towards Ash Tree Farm and Ash Plantation. It widens slightly and begins to cross open countryside, slowly turning southeast again. Along this section,

1313-478: A water wheel. The mechanical engineer Ma Jun (c. 200–265) from Cao Wei once used a water wheel to power and operate a large mechanical puppet theater for the Emperor Ming of Wei ( r. 226–239). The technological breakthrough occurred in the technologically developed Hellenistic period between the 3rd and 1st century BC. A poem by Antipater of Thessalonica praised the water wheel for freeing women from

1414-451: A yeoman farmer, who was joined by recruits from Norwich and the surrounding countryside. His group numbered some 16,000 by the time the rebels stormed Norwich on 29 July 1549 and took the city. Kett's rebellion ended on 27 August when the rebels were defeated by an army under the leadership of John Dudley, 1st Duke of Northumberland at the Battle of Dussindale. Some 3,000 rebels were killed. Kett

1515-504: Is a non-metropolitan county with seven districts. The west of Norfolk is part of the Fens , an extremely flat former marsh. The centre of the county is gently undulating lowland; its northern coast is an area of outstanding natural beauty , and in the south is part of Thetford Forest . In the east are the Broads , a network of rivers and lakes which extend into Suffolk. The area is protected by

1616-434: Is a small stream with a height difference of more than 2 metres (6.5 ft), often in association with a small reservoir. Breastshot and undershot wheels can be used on rivers or high volume flows with large reservoirs. A horizontal wheel with a vertical axle. Commonly called a tub wheel , Norse mill or Greek mill , the horizontal wheel is a primitive and inefficient form of the modern turbine. However, if it delivers

1717-452: Is a vertically mounted water wheel with a horizontal axle that is rotated by the water from a low weir striking the wheel in the bottom quarter. Most of the energy gain is from the movement of the water and comparatively little from the head. They are similar in operation and design to stream wheels. The term undershot is sometimes used with related but different meanings: This is the oldest type of vertical water wheel. The word breastshot

1818-532: Is administered by Norfolk County Council, which is the top tier local government authority, based at County Hall in Norwich. For details of the authority click on the link Norfolk County Council . Below Norfolk County Council the county is divided into seven second tier district councils: Breckland District , Broadland District , Great Yarmouth Borough , King's Lynn and West Norfolk Borough , North Norfolk District , Norwich City and South Norfolk District . Below

1919-586: Is assumed that the scientists of the Museum of Alexandria , at the time the most active Greek research center, may have been involved in its invention. An episode from the Alexandrian War in 48 BC tells of how Caesar's enemies employed geared waterwheels to pour sea water from elevated places on the position of the trapped Romans. Around 300 AD, the noria was finally introduced when the wooden compartments were replaced with inexpensive ceramic pots that were tied to

2020-596: Is controlled by the Labour Party and North Norfolk District by the Liberal Democrats . Norfolk County Council has been under Conservative control since 2017. There have been two periods when the council has not been run by the Conservative Party, both when no party had overall control, these were 1993–2001 and 2013–2017.

2121-574: Is largely based on agriculture and tourism. The area that was to become Norfolk was settled in pre-Roman times (there were Palaeolithic settlers as early as 950,000 years ago), with camps along the higher land in the west, where flints could be quarried. A Brittonic tribe, the Iceni , emerged in the 1st century BC . The Iceni revolted against the Roman invasion in AD 47, and again in 60 led by Boudica . The crushing of

2222-405: Is quite possible the water was diverted to this point for the purpose of driving the mill. Unusually the mill had an overshot waterwheel . The only way to provide a sufficient head of water was to dam the river to form the mill pond we see today which is some considerable height above the road. When the mill was working, 8 million gallons of water flowed through per day. When the mill was worked by

2323-420: Is rotated by the water in a water course striking paddles or blades at the bottom of the wheel. This type of water wheel is the oldest type of horizontal axis wheel. They are also known as free surface wheels because the water is not constrained by millraces or wheel pits. Stream wheels are cheaper and simpler to build and have less of an environmental impact than other types of wheels. They do not constitute

2424-492: Is served by these local newspapers: Before 2011, Norfolk had a completely comprehensive state education or "maintained" system managed by Norfolk County Council , with secondary school age from 11 to 16 or in some schools with sixth forms , 18 years old. Since then, a number of schools formerly in the "maintained" system have left it to become academies , or members of academy groups. Others have become free schools . Both academies and free schools are still publicly funded by

2525-408: Is the overhead timber structure and a branch to the left supplies water to the wheel. The water exits from under the wheel back into the stream. A special type of overshot/backshot wheel is the reversible water wheel. This has two sets of blades or buckets running in opposite directions so that it can turn in either direction depending on which side the water is directed. Reversible wheels were used in

2626-479: Is used in a variety of ways. Some authors restrict the term to wheels where the water enters at about the 10 o’clock position, others 9 o’clock, and others for a range of heights. In this article it is used for wheels where the water entry is significantly above the bottom and significantly below the top, typically the middle half. They are characterized by: Both kinetic (movement) and potential (height and weight) energy are utilised. The small clearance between

2727-473: The Ancient Near East before Alexander's conquest can be deduced from its pronounced absence from the otherwise rich oriental iconography on irrigation practices. Unlike other water-lifting devices and pumps of the period though, the invention of the compartmented wheel cannot be traced to any particular Hellenistic engineer and may have been made in the late 4th century BC in a rural context away from

2828-517: The Broads Authority and has similar status to a national park . The geology of the county includes clay and chalk deposits, which make its coast susceptible to erosion. There is evidence of Prehistoric settlement in Norfolk. In the Roman era the region was home to the Iceni , whose leader Boudica led a major revolt in AD60. The Angles settled the area in the fifth century, and it became part of

Following the 2010 general election , Eric Pickles was appointed Secretary of State for Communities and Local Government on 12 May 2010 in a Conservative–Liberal Democrat coalition government . According to press reports, he instructed his department to take urgent steps to reverse the decision and maintain

3030-586: The Fall Line of the North American East Coast. Breastshot wheels are the most common type in the United States of America and are said to have powered the industrial revolution. A vertically mounted water wheel that is rotated by water entering buckets just past the top of the wheel is said to be overshot. The term is sometimes, erroneously, applied to backshot wheels, where the water goes down behind

3232-575: The Kingdom of East Anglia . During the later Middle Ages the county was very prosperous and heavily involved in the wool trade ; this allowed the construction of many large churches . In 1549 Norfolk was the scene of Kett's Rebellion , which unsuccessfully protested the enclosure of land. The county was not heavily industrialised during the Industrial Revolution , and Norwich lost its status as one of England's largest cities. The contemporary economy

3535-540: The copper mines at Rio Tinto in Spain , one system involving 16 such wheels stacked above one another so as to lift water about 80 feet from the mine sump. Part of such a wheel was found at Dolaucothi , a Roman gold mine in south Wales in the 1930s when the mine was briefly re-opened. It was found about 160 feet below the surface, so must have been part of a similar sequence as that discovered at Rio Tinto. It has recently been carbon dated to about 90 AD, and since

3636-414: The mining industry in order to power various means of ore conveyance. By changing the direction of the wheel, barrels or baskets of ore could be lifted up or lowered down a shaft or inclined plane. There was usually a cable drum or a chain basket on the axle of the wheel. It is essential that the wheel have braking equipment to be able to stop the wheel (known as a braking wheel). The oldest known drawing of

In the mid- to late 18th century John Smeaton 's scientific investigation of the water wheel led to significant increases in efficiency, supplying much-needed power for the Industrial Revolution . Water wheels began being displaced by the smaller, less expensive and more efficient turbine , developed by Benoît Fourneyron , beginning with his first model in 1827. Turbines are capable of handling high heads , or elevations , that exceed

Several place names around the Fenland area contain Celtic elements; this has been taken by some scholars to represent a possibly significant concentration of Britons in the area. In the centuries before the Norman Conquest the wetlands of the east of the county began to be converted to farmland, and settlements grew in these areas. Migration into East Anglia must have been high: by

4242-549: The Larter family in the 1920s, the deeds stated that anyone interfering with the river had to pay dues to the millers. The Larter family also used the mill to generate electricity, which also supplied power to some of the surrounding properties including a Bell's grocery shop, Larter & Rudran's bicycle garage and a property at The Dell. The mill burnt down in November 1956. Some of the cog wheels were still visible in their mountings within

4343-576: The Mun runs adjacent to several small reservoirs, ponds and drains. At Gimingham the river flows into a series of mill ponds . The ponds once fed a watermill, whose dam held back a 20-acre (81,000 m) broad fed by the River. There has been a mill at the location since the time of the Domesday Book . The watermill was worked in conjunction with the nearby Gimingham postmill until 1877. The original waterwheel

4444-520: The Norfolk Chamber of Commerce made this comment: "At a time when Norfolk firms face steep up-front costs, the apprenticeship system is in crisis, roads are being allowed to crumble, mobile phone and broadband 'not-spots' are multiplying, it's obvious that the key to improved productivity and competitiveness lies in getting the basics right". The solution was seen as a need for the UK government to provide "a far stronger domestic economic agenda ... to fix

4545-469: The advantage that the bottom of the wheel is moving in the same direction as the water in the tailrace which makes it more efficient. It also performs better than an overshot wheel in flood conditions when the water level may submerge the bottom of the wheel. It will continue to rotate until the water in the wheel pit rises quite high on the wheel. This makes the technique particularly suitable for streams that experience significant variations in flow and reduces

4646-555: The announcement, Norfolk County Council issued a statement that it would seek leave to challenge the decision in the courts. A letter was leaked to the local media in which the Permanent Secretary for the Department for Communities and Local Government noted that the decision did not meet all the criteria and that the risk of it "being successfully challenged in judicial review proceedings is very high". The Shadow Local Government and Planning Minister, Bob Neill , stated that should

4747-442: The bottom of a water-filled, circular shaft. The water from the mill-race which entered tangentially the pit created a swirling water column that made the fully submerged wheel act like true water turbines , the earliest known to date. Apart from its use in milling and water-raising, ancient engineers applied the paddled waterwheel for automatons and in navigation. Vitruvius (X 9.5–7) describes multi-geared paddle wheels working as

4848-413: The capability of practical-sized waterwheels. The main difficulty of water wheels is their dependence on flowing water, which limits where they can be located. Modern hydroelectric dams can be viewed as the descendants of the water wheel, as they too take advantage of the movement of water downhill. Water wheels come in two basic designs: The latter can be subdivided according to where the water hits

4949-591: The city centre, next to the River Wensum . The City College Norwich and the College of West Anglia are colleges covering Norwich and King's Lynn as well as Norfolk as a whole. Easton & Otley College , 7 mi (11 km) west of Norwich, provides agriculture-based courses for the county, parts of Suffolk , and nationally. The University of Suffolk also runs higher education courses in Norfolk, from multiple locations including Great Yarmouth College . Norfolk

Norfolk is also home to Wymondham College , the UK's largest remaining state boarding school . The University of East Anglia is located on the outskirts of Norwich, and Norwich University of the Arts is based in seven buildings in and around St George's Street in

5151-597: The coastal village of Mundesley . The valley here is part of Mundesley Golf Club . The golf club was established in 1901, and was designed with the help of one of the sport's legends, 6-times Open winner Harry Vardon (1870–1937), built on the rolling hillside of the River Mun valley. Today its nine holes, with 18 tees, offer a satisfying challenge to players of all abilities. Harry Vardon's association with Mundesley Golf Club spanned many years, from consultation, in 1900 to his misfortune to contract tuberculosis in 1903, and it

5252-400: The combination of the separate Greek inventions of the toothed gear and the waterwheel into one effective mechanical system for harnessing water power. Vitruvius' waterwheel is described as being immersed with its lower end in the watercourse so that its paddles could be driven by the velocity of the running water (X, 5.2). About the same time, the overshot wheel appears for the first time in

5353-500: The county's economy. The median hourly gross pay was £12.17 and the median weekly pay was £496.80; on a per year basis, the median gross income was £25,458. The employment rate among persons aged 16 to 64 was 74.2% while the unemployment rate was 4.6%. The Norfolk economy was "treading water with manufacturing sales and recruitment remaining static in the first quarter of the year" according to research published in April 2018. A spokesperson for

5454-591: The departure of the Romans. Soon afterward, Germanic peoples from the North Sea area settled in the region. Though they became known as Angles , they were likely not affiliated to any tribe in particular at the time of their migration. It is thought that the settlement here was early (possibly beginning at the start of the fifth century, thereby preceding the alleged date of Hengist and Horsa 's arrival in Kent) and that it occurred on

5555-722: The energy is gained from the weight of water lowered to the tailrace although a small contribution may be made by the kinetic energy of the water entering the wheel. They are suited to larger heads than the other type of wheel so they are ideally suited to hilly countries. However even the largest water wheel, the Laxey Wheel in the Isle of Man , only utilises a head of around 30 m (100 ft). The world's largest head turbines, Bieudron Hydroelectric Power Station in Switzerland , utilise about 1,869 m (6,132 ft). Overshot wheels require

5656-416: The exhausting labor of milling and grinding. The compartmented water wheel comes in two basic forms, the wheel with compartmented body ( Latin tympanum ) and the wheel with compartmented rim or a rim with separate, attached containers. The wheels could be either turned by men treading on its outside or by animals by means of a sakia gear. While the tympanum had a large discharge capacity, it could lift

5757-650: The fundamentals needed for business to thrive here..." In 2017, tourism was adding £3.25 billion to the economy per year and supported some 65,000 jobs, being the fifth most important employment in Norfolk. The visitor economy had increased in value by more than £500 million since 2012. Important business sectors also include energy (oil, gas and renewables), advanced engineering and manufacturing, and food and farming. Much of Norfolk's fairly flat and fertile land has been drained for use as arable land . The principal arable crops are sugar beet , wheat, barley (for brewing) and oil seed rape . The county also boasts

5858-474: The greatest concentration in the world. The economy was in decline by the time of the Black Death , which dramatically reduced the population in 1349. Kett's Rebellion occurred in Norfolk during the reign of Edward VI , largely in response to the enclosure of land by landlords, leaving peasants with nowhere to graze their animals, and to the general abuses of power by the nobility. It was led by Robert Kett ,

The local British Army regiments included the Royal Norfolk Regiment (now the Royal Anglian Regiment ) and the Norfolk Yeomanry . During the Second World War agriculture rapidly intensified, and it has remained very intensive since, with the establishment of large fields for growing cereals and oilseed rape . In 1998 Norfolk had

It shows a pair of yoked oxen driving the wheel via a sakia gear, which is here for the first time attested, too. The Greek sakia gear system is already shown fully developed to the point that "modern Egyptian devices are virtually identical". It

They were reverse overshot water-wheels designed for dewatering deep underground mines. Several such devices are described by Vitruvius , including the reverse overshot water-wheel and the Archimedean screw . Many were found during modern mining at

6666-470: The palace of the Pontian king Mithradates VI Eupator , but its exact construction cannot be gleaned from the text (XII, 3, 30 C 556). The first clear description of a geared watermill offers the late 1st century BC Roman architect Vitruvius who tells of the sakia gearing system as being applied to a watermill. Vitruvius's account is particularly valuable in that it shows how the watermill came about, namely by

6767-418: The pestle and mortar, which is so useful, and later on it was cleverly improved in such a way that the whole weight of the body could be used for treading on the tilt-hammer ( tui ), thus increasing the efficiency ten times. Afterwards the power of animals—donkeys, mules, oxen, and horses—was applied by means of machinery, and water-power too used for pounding, so that the benefit was increased a hundredfold. In

Early military units included the Norfolk Militia . In the 20th century the county developed a role in aviation. The first development in airfields came with the First World War ; there was then a massive expansion during the Second World War with

Situated on the east coast, the homelands of the Iceni were vulnerable to attacks from continental Europe and other parts of Britain, and forts were built to defend against raids by the Saxons and the Picts . A period of depopulation, which may have been due to these threats, seems to have followed

7474-443: The second tier councils the majority of the county is divided into parish and town councils, the lowest tier of local government (the only exceptions being parts of Norwich and King's Lynn urban areas). Currently the Conservative Party control five of the seven district councils: Breckland District , Broadland District , King's Lynn and West Norfolk Borough , Great Yarmouth Borough and South Norfolk District while Norwich City

7575-508: The shell of the building in 1959. The remains of the building were finally pulled down in the summer of 1965. The waterwheel was large with a diameter of 26 feet (7.9 m) and the owner of the Mill House decided to enclose the wheel behind a grill and to leave it as a showpiece. The wooden spokes and the rim can still be seen, and some of the metal scoops and some wooden cogs have been replaced. For many years it still turned whenever enough water

7676-474: The size, complexity, and hence cost of the tailrace. The direction of rotation of a backshot wheel is the same as that of a breastshot wheel but in other respects, it is very similar to the overshot wheel. See below. Some wheels are overshot at the top and backshot at the bottom thereby potentially combining the best features of both types. The photograph shows an example at Finch Foundry in Devon, UK. The head race

7777-407: The south. The largest settlement is the city of Norwich . The county has an area of 2,074 sq mi (5,370 km ) and a population of 859,400. It is largely rural with few large towns: after Norwich (147,895), the largest settlements are King's Lynn (42,800) in the north-west, Great Yarmouth (38,693) in the east, and Thetford (24,340) in the south. For local government purposes Norfolk

7878-561: The status quo in line with the Conservative Party manifesto. However, the unitary plans were supported by the Liberal Democrat group on the city council, and by Simon Wright , LibDem MP for Norwich South , who intended to lobby the party leadership to allow the changes to go ahead. The Local Government Act 2010 to reverse the unitary decision for Norwich (and Exeter and Suffolk) received Royal Assent on 16 December 2010. The disputed award of unitary status had meanwhile been referred to

7979-466: The stretch of coast will be protected for at least another 50 years, but that in the event of sea level rise and post-glacial lowering of land levels in the South East, there may a need for further research to inform future management decisions, including the possibility that the sea defences may have to be realigned to a more sustainable position. Natural England have contributed some research into

8080-530: The time of the Domesday Book survey it was one of the most densely populated parts of the British Isles . During the high and late Middle Ages the county developed arable agriculture and woollen industries. Norfolk's prosperity at that time is evident from the county's large number of medieval churches: out of an original total of over one thousand some 659 have survived, more than in any other county in Britain and

8181-458: The urban constituencies they once held in Norwich North and Great Yarmouth, leaving them with no MP's in the whole of East Anglia ; the former Labour Home Secretary Charles Clarke was a high level casualty of that election. In the 2015 General Election seven seats were won by the Conservative Party , with Labour winning Norwich South and the Liberal Democrats winning North Norfolk. In

8282-451: The use of such wheels for submerging siege mines as a defensive measure against enemy sapping. Compartmented wheels appear to have been the means of choice for draining dry docks in Alexandria under the reign of Ptolemy IV (221−205 BC). Several Greek papyri of the 3rd to 2nd century BC mention the use of these wheels, but do not give further details. The non-existence of the device in

8383-444: The usurpation of Wang Mang ), it states that the legendary mythological king known as Fu Xi was the one responsible for the pestle and mortar, which evolved into the tilt-hammer and then trip hammer device (see trip hammer ). Although the author speaks of the mythological Fu Xi, a passage of his writing gives hint that the water wheel was in widespread use by the 1st century AD in China ( Wade-Giles spelling): Fu Hsi invented

8484-448: The vertical-axle waterwheel. In the 2nd century AD Barbegal watermill complex a series of sixteen overshot wheels was fed by an artificial aqueduct, a proto-industrial grain factory which has been referred to as "the greatest known concentration of mechanical power in the ancient world". In Roman North Africa , several installations from around 300 AD were found where vertical-axle waterwheels fitted with angled blades were installed at

8585-425: The village under Trunch Road close to its junction with High Street and Heath Road. Just past Trunch Road the river falls over another weir before turning north into the eastern side of the village. The river now fills another mill pond where once the second mill on the river worked. Mundesley watermill was built c.1723 and consisted of two brick floors supporting a weather boarded upper floor and roof space under

8686-520: The water flowing to or from a water wheel is called a mill race . The race bringing water from the mill pond to the water wheel is a headrace ; the one carrying water after it has left the wheel is commonly referred to as a tailrace . Waterwheels were used for various purposes from things such as agriculture to metallurgy in ancient civilizations spanning the Hellenistic Greek world , Rome , China and India . Waterwheels saw continued use in

8787-416: The water hits the wheel paddles, into overshot, breastshot and undershot wheels. The two main functions of waterwheels were historically water-lifting for irrigation purposes and milling, particularly of grain. In case of horizontal-axle mills, a system of gears is required for power transmission, which vertical-axle mills do not need. The earliest waterwheel working like a lever was described by Zhuangzi in

8888-556: The water only to less than the height of its own radius and required a large torque for rotating. These constructional deficiencies were overcome by the wheel with a compartmented rim which was a less heavy design with a higher lift. The earliest literary reference to a water-driven, compartmented wheel appears in the technical treatise Pneumatica (chap. 61) of the Greek engineer Philo of Byzantium ( c.  280  – c.  220 BC ). In his Parasceuastica (91.43−44), Philo advises

8989-481: The wheel and the masonry requires that a breastshot wheel has a good trash rack ('screen' in British English) to prevent debris from jamming between the wheel and the apron and potentially causing serious damage. Breastshot wheels are less efficient than overshot and backshot wheels but they can handle high flow rates and consequently high power. They are preferred for steady, high-volume flows such as are found on

9090-423: The wheel into backshot (pitch-back ), overshot, breastshot, undershot, and stream-wheels. The term undershot can refer to any wheel where the water passes under the wheel but it usually implies that the water entry is low on the wheel. Overshot and backshot water wheels are typically used where the available height difference is more than a couple of meters. Breastshot wheels are more suited to large flows with

9191-457: The wheel. A typical overshot wheel has the water channeled to the wheel at the top and slightly beyond the axle. The water collects in the buckets on that side of the wheel, making it heavier than the other "empty" side. The weight turns the wheel, and the water flows out into the tail-water when the wheel rotates enough to invert the buckets. The overshot design is very efficient, it can achieve 90%, and does not require rapid flow. Nearly all of

9292-449: The wood from which it was made is much older than the deep mine, it is likely that the deep workings were in operation perhaps 30–50 years after. It is clear from these examples of drainage wheels found in sealed underground galleries in widely separated locations that building water wheels was well within their capabilities, and such verticals water wheels commonly used for industrial purposes. Taking indirect evidence into account from

9393-505: The work of the Greek technician Apollonius of Perge , the British historian of technology M.J.T. Lewis dates the appearance of the vertical-axle watermill to the early 3rd century BC, and the horizontal-axle watermill to around 240 BC, with Byzantium and Alexandria as the assigned places of invention. A watermill is reported by the Greek geographer Strabon ( c.  64 BC  – c.  AD 24 ) to have existed sometime before 71 BC in

9494-574: The year 31 AD, the engineer and Prefect of Nanyang , Du Shi (d. 38), applied a complex use of the water wheel and machinery to power the bellows of the blast furnace to create cast iron . Du Shi is mentioned briefly in the Book of Later Han ( Hou Han Shu ) as follows (in Wade-Giles spelling): In the seventh year of the Chien-Wu reign period (31 AD) Tu Shih was posted to be Prefect of Nanyang. He

9595-425: Was a generous man and his policies were peaceful; he destroyed evil-doers and established the dignity (of his office). Good at planning, he loved the common people and wished to save their labor. He invented a water-power reciprocator ( shui phai ) for the casting of (iron) agricultural implements. Those who smelted and cast already had the push-bellows to blow up their charcoal fires, and now they were instructed to use

9696-502: Was available. The river's water flowed over the wheel and then under the road and into the North sea through a pipe. Norfolk Norfolk ( / ˈ n ɔːr f ə k / NOR -fək ) is a ceremonial county in the East of England and East Anglia . It borders Lincolnshire and The Wash to the north-west, the North Sea to the north and east, Cambridgeshire to the west, and Suffolk to

9797-506: Was being established by business leaders to help grow jobs across Norfolk and Suffolk. They secured an enterprise zone to help grow businesses in the energy sector, and established the two counties as a centre for growing services and products for the green economy . To help local industry in Norwich, the local council offered a wireless internet service, but this was subsequently withdrawn as funding had ceased. The fishery business still continued in 2018, with individuals such as John Lee,

9898-628: Was captured, held in the Tower of London, tried for treason, and hanged from the walls of Norwich Castle. By the late 16th century Norwich had grown to become the second-largest city in England, but over one-third of its population died in the plague epidemic of 1579, and in 1665 the Great Plague again killed around one-third of the population. During the English Civil War Norfolk was largely Parliamentarian . The economy and agriculture of

9999-411: Was later supplemented by steam, then replaced by a turbine in 1912 and later by diesel engines , although water was still used for cooling them. It milled animal feedstuffs until 30 November 1976. The diesel engine has been preserved and stands on Mill Street. Gimingham Mill Lake is a popular fishing location. Bream , carp , tench and roach can be caught.In the lake, pit and river, From Gimingham

10100-558: Was rejected in December 2007 as it did not meet the criteria for acceptance. In February 2008, the Boundary Committee for England (from 1 April 2010 incorporated in the Local Government Boundary Commission for England ) was asked to consider alternative proposals for the whole or part of Norfolk, including whether Norwich should become a unitary authority , separate from Norfolk County Council. In December 2009,

10201-416: Was to Mundesley's sanatorium that he went for treatment. While recuperating in 1904, still at the sanatorium, he ventured along the lane which bisects the course to enjoy a round of golf. Here he experienced his only career hole-in-one, on what is now the sixth, a feat which no doubt contributed to the success of his convalescence. From the golf course the river travels a short distance due east and enters
