Problem: Find valve size and valve position of an unlined valve, with flow at 200 gpm and an actual pressure drop of 5 psi for a liquid with a specific gravity of 1.8. Solution: Cv =200 √1.8/5 = 200 √.36 = (200)(0.6) = 120 From Cv Table: A 2" valve has a Cv of 120 at 40% ... The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: … See more The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ).
