Cv to k factor

WebThe flow factor, or flow coefficient of a valve shows the relationship between the pressure drop and the flow rate. K v is the flow coefficient in metric units, and can be calculated with the following equation: where . K V: Flow factor (m 3 ·h-1 ·bar-0.5) Q: Flow rate (m 3 /h) SG: Specific Gravity of the liquid (dimensionless). For water SG=1 WebCv = 1.156 * Kv. OR Kv = 0.864 * Cv The flow rate for a liquid Q = Cv * Sq. Root of ( ΔP/SG) Q = Flow in US GPM. Cv = Flow Coefficient of control valve ΔP = Differential pressure SG = Specific Gravity of fluid (reference …
