Flow rate calculation cv

WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { \frac {SG} { \Delta P}} K v = Q ΔP SG. Where Q is in m 3 /hr and ΔP is in bar. Thus for a given K v, ρ and Q the ... 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
