degree of water
61degree — 1) 1/360 of a circle or 60 minutes. The symbol here and below is ° 2) 60 nautical miles, 69.05 statute miles or 111.12 km 3) a temperature unit (Celsius or Fahrenheit). Strictly 10°C is an actual temperature while 10C° is a range (from say 23 to… …
62degree Baumé — (°B or °Bé) a unit of relative density, as read on a type of hydrometer invented by the French chemist Antoine Baumé (1728 1804). Two scales are used, depending on whether the liquid is lighter than water or heavier than water. For lighter… …
63degree Réaumur — (°r or °R) a unit of temperature formerly used in continental Europe. The Réaumur temperature scale is named for the French scientist René Antoine Ferchault de Réaumur (1683 1757). It is similar to the Celsius scale in having its zero point at …
64degree Fahrenheit — (°F) a traditional unit of temperature still used customarily in the United States. The unit was defined by the German physicist Daniel G. Fahrenheit (1686 1736), who also invented the mercury thermometer. Fahrenheit set 0° at the coldest… …
65Well water for cooling — A means of cooling that uses water from a well drilled specifically for that purpose. The subterranean temperature of the water stays at a relatively constant temperature. Where water is abundant, it provides a means of getting 55 degree… …
66Hard water — is the type of water that has high mineral content (in contrast with soft water ). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) metal cations, and sometimes other dissolved compounds such as bicarbonates and… …
67Superheated water — is liquid water under pressure at temperatures between the usual boiling point (100°C) and the critical temperature (374°C). It is also known as subcritical water and pressurised hot water. Superheated water referred to in this article is stable… …
68Properties of water — H2O and HOH redirect here. For other uses, see H2O (disambiguation) and HOH (disambiguation). This article is about the physical and chemical properties of pure water. For general discussion and its distribution and importance in life, see Water …
69Erosion corrosion of copper water tubes — Erosion corrosion, also known as impingement damage, is the combined effect of corrosion and erosion caused by rapid flowing turbulent water. It is probably the second most common cause of copper tube failures behind Type 1 pitting which is also… …
70API oil-water separator — An API oil water separator is a device designed to separate gross amounts of oil and suspended solids from the wastewater effluents of oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial… …
