Cv meaning flow
WebFlow Calculation for Gases The coefficient of flow (Cv) is a formula which is used to determine a valve’s flows under various conditions and to select the correct valve for a flow application. The Cv was designed for use with liquid flows, it expresses the flow in gallons per minute of 60º F water with a pressure drop across the valve of 1 psi. WebMar 17, 2015 · In practical terms, the lower the number the less the variation there is. To think why CV is generally a better measure for comparing across platforms, consider two distributions that have the same relative spread of about 10%. If the mean of one is 100, it will spread between 90 and 100, but if the mean is 1000, it will spread between 900 and ...
