WebFeb 21, 2024 · C = Q/N1 * √ (ρ1/ρ0) / (∆P) C is the Flow Coefficient which describes how much fluid will flow through the valve for a given pressure drop. Q is the Flow Rate (m3/h, GPM, SCFH). ∆P is the differential pressure between upstream and downstream pressure taps (kPa, bar, psi). ρ1/ρ0 is the relative density. WebCV Calculator / Regulator Flow Curve. Use caution when applying these results to a pressure regulator. The Cv of a regulator represents its FULLY OPEN flow capacity, while a regulator is never intended to be used at that point. Multiply the results by 1.5 for a margin of safety and consult the product's flow curves in the product literature. how are asteroids and planets similar
