WebPressure drop (often abbreviated as "dP" or "ΔP") is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through a conduit (such as a channel, pipe, or tube).This friction converts some of the fluid’s hydraulic … WebThe pressure drop or rather pressure difference dP (it could be a gain) between the start and the end of a pipe is therefore given by this equation: dP = Friction Loss + Fittings Loss + Component Loss - Elevation [start …
