What is Pressure Drop? To determine Delta P across a valve, subtract the outlet pressure (P2) from the inlet pressure (P1). The equation is (P1) – (P2) = P.
22 wrz 2023 · The pressure drop across a valve can be calculated using the following general formula: Pressure Drop (ΔP) = K × Q² Where: ΔP is the pressure drop (in psi). K is the valve’s pressure drop coefficient. Q is the flow rate (in gallons per minute, GPM).
By taking into account units of measurement, the proportionality relationship previously mentioned, energy losses due to friction and turbulence, and varying discharge coeficients for various types of orifices (or valve bodies), a basic liquid sizing equation can be written as follows. Q = C.
