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 The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ). Q is the flowrate (expressed in cubic metres per hour m ·h ), SG is the specific gravity of the fluid (for water = 1), ∆P is the differential pressure across the device (expressed in bar).
