Flow Coefficient of Air and Gases for Non-Critical Pressure Drop

The flow coefficient of air and gas when there is non-critical pressure drop can be calculated using the inlet and outlet gas absolute pressure, specific gravity, temperature and free gas / standard cubic feet per hour.

Formula:

dp = (pi - po) Cv = (q [SG (T + 460)]1/2)/ [1360 (dp * po)(1/2)] 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 po = Outlet Gas Absolute Pressure dp = Pressure Drop
