Saline water (more commonly known as salt water ) is water that contains a high concentration of dissolved salts (mainly sodium chloride ). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water , but less salty than brine . The salt concentration is usually expressed in parts per thousand (permille, ‰) and parts per million (ppm). The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1,000 to 3,000 ppm (0.1–0.3%); in moderately saline water is 3,000 to 10,000 ppm (0.3–1%); and in highly saline water is 10,000 to 35,000 ppm (1–3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is only nominally dependent on the temperature of the water. At 20 °C (68 °F) one liter of water can dissolve about 357 grams of salt, a concentration of 26.3 percent by weight (% w/w). At 100 °C (212 °F) (the boiling temperature of pure water), the amount of salt that can be dissolved in one liter of water increases to about 391 grams, a concentration of 28.1% w/w.
5-528: The Avoca Lake , formerly known as Avoca Lagoon and as Bulbararing Lagoon , is an intermittently closed intermediate saline coastal lagoon that is located on the Central Coast of New South Wales , Australia . Avoca Lake is located between the beachside settlements of North Avoca and Avoca Beach , and adjacent to the Pacific Ocean , about 85 kilometres (53 mi) north of Sydney . The Avoca Lake
10-430: A salinometer . Density ρ of brine at various concentrations and temperatures from 200 to 575 °C (392 to 1,067 °F) can be approximated with a linear equation: ρ [ l b / f t 3 ] = a 3 − ( a 2 ⋅ T [ F ] ) {\displaystyle \rho [lb/ft^{3}]=a_{3}-(a_{2}\cdot T[F])} where
15-463: Is about 28% salt by weight. At 0 °C (32 °F; 273 K), brine can only hold about 26% salt. At 20 °C one liter of water can dissolve about 357 grams of salt, a concentration of 26.3%. The thermal conductivity of seawater (3.5% dissolved salt by weight) is 0.6 W/mK at 25 °C (77 °F). The thermal conductivity decreases with increasing salinity and increases with increasing temperature. The salt content can be determined with
20-614: Is fed by stormwater runoff into Saltwater Creek that gathers on the slopes within Kincumber Mountain Reserve to the northwest above Pickets Valley. The lake has a surface area of approximately 70 hectares (170 acres) and a catchment area of 10.8 square kilometres (4.2 sq mi). Its outflow is into Bulbararing Bay in the Tasman Sea of the South Pacific Ocean . The outflow is generally closed, and water levels inside
25-455: The lake are not usually influenced by ocean tides. Bareena Island lies entirely within Avoca Lake. Terrigal Lagoon and Wamberal Lagoon are located to the north and are a short distance away.
