The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is defined as one newton per square metre. It is named after the French polymath Blaise Pascal.
Phosphate Ester Fluids - Benefits and Limitations. Since the discovery of their excellent anti-wear and fire resistance properties in the 1940s, the use of phosphate esters by industry has steadily increased. Phosphate esters are used primarily as fire-resistant basestocks in several applications including hydraulic systems, turbines and compressors.
Phosphates are the food supply for algae, thus high phosphate levels promote algae growth. When you introduce phosphate reducers into your water, such as Natural Chemistry PHOSfree 2 L, it cuts off the food supply for algae, which can, in turn, lead to cloudy water (filled with dead algae).
