11 Calculation Formula Cv = WATER CAPACITY IN GPM WITH A PRESSURE DROP OF 1 P.S.I The formulas for sizing control valves are based on fluid controls Standard FCI The Cv number of a valve is its flow coefficient and used to determine the maximum valve capacity for any condition using the formulas below. Cv = Valve Coefficient Q = Flow in Gallons per Minute P = Pressure Drop Q 1 = Flow Cubic Feet per Hour P 1 = Inlet pressure Absolute (PSIA) G = Specific Gravity (Water = 1) P 2 = Outlet pressure Absolute G 1 = Specific Gracity (Air = o F) W = 1bs. per hour satuated steam T = Absolute Temperature of Flowing Medium (F 460) STEAM) - When P < P 1 /2 When P > P 1 /2 W = 2.1 x Cv P P 1 + P 2 W = 1.82 x Cv X P 1 Cv = W 1 Cv = W 2.1 P(P 1 + P 2 ) 1.82 x P 1 AIR) - When P < P 1 /2 When P > P 1 /2 Q 1 = 963 x Cv P(P 1 + P 2 ) Cv = 832 x Cv x P 1 G 1 x T G 1 x T Cv = Q1 G 1 x T Cv = Q1 G1 x T 963 P (P 1 +P 2 ) 832 x P 1 WATER) Q = Cv P Cv = Q G G P W = Max flow capacity of steam Q = Max flow capacity of gas (NM3/hr) P 1 = Inlet pressure (kgf/cm 2 abs) P 2 = Outlet pressure (kgf/cm 2 ) P = P 1 - P 2 (kgf/cm 2 abs) K = x [(Super heated steam) temp.
