DC Water and EPA agreed upon new nitrogen limits as part of the NPDES permit effective September 2010, reducing nitrogen levels to 4.7 million pounds per year. DC Water plans to achieve these levels by constructing new facilities at Blue Plains to perform enhanced nitrogen removal (ENR). The total cost of the project is nearly $1 billion. [15]
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...

A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s, e.g. water. [clarify]
