ABOUT Cv (FLOW COEFFICIENTS) FNW Valve Q = Cv x ΔP x 62.4 D The formula above utilizes a conversion factor of 62.4 which is the density of water in lbs ft³. The following formula is often used using a fluid’s specific gravity (G) where the relationship to water density is already considered. Q = Cv x ΔP G Likewise, Cv for particular flow characteristics can be determined from Cv and Kv Flow Coefficients Pipe Flow Software The adjusted Cv (or Kv) value should be based on the Cv or Kv formula for sub critical gas pressure drop. A simplified version of the Cv formula for sub critical gas pressure drop is shown below: Where: Cv = flow coefficient. SCFH = flow rate in ft 3 hr (NTP) D n = the gas density in lbs ft 3 at 0.00 psig. o F = gas temperature Resistance Coefficient K from Cv or Kv Engineered ... Calculating Resistance Coefficient K from C v or K v. by Engineered Software, Inc. For control valves, the valve capacity and flow characteristics are typically expressed in terms of a valve flow coefficient (C v).This article discusses how this flow coefficient can be used to calculate the equivalent resistance coefficient, or K value, used in the Darcy Weisbach equation.
