What is CV and how is it calculated?
The standard formula for calculating the coefficient of variation is as follows: Coefficient of Variation (CV) = (Standard Deviation/Mean) × 100.
What is the CV calculation of a control valve?
The volume flow rate for liquids can be calculated by multiplying the fluid velocity times the flow area. Thus, Cv is numerically equal to the number of U.S. gallons of water at 60°F that will flow through the valve in one minute when the pressure differential across the valve is one pound per square inch.
What is CV in measurement?
The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage.
