The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: … See more 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 … See more • Discharge coefficient See more WebJan 28, 2024 · Cv is based on the volume flow rate of water at 60°F through a device within one minute at a 1 psi differential. However, there is a problem with using this equation in pneumatic applications. Because air is compressible, Cv must have additional factors built into the equations to compensate for that compressibility.
