Flow Coefficient of Air Calculator

At stifled flow the critical pressure drop the outlet pressure from the control valve is short of what 58% of the inlet pressure. Obtain the flow coefficient for air (gases) in critical pressure drop based on the steam flow and the inlet steam pressure.

Formula:

Cv = (q [SG (T + 460)]1/2) / (660 * pi) Where, Cv = Flow Coefficient for Air and Other Gases q = Free Gas / Standard Cubic Feet Per Hour SG = Specific Gravity T = Gas Temperature pi = Inlet Gas Absolute Pressure
