WebThe head loss (or the pressure loss) due to fluid friction (H friction) represents the energy used in overcoming friction caused by the pipe walls. The head loss that occurs in pipes is dependent on the flow velocity, pipe diameter, and length , and a friction factor based on the roughness of the pipe and the Reynolds number of the flow. WebMinor head losses are a function of: flow regime (i.e., Reynolds number) flow velocity. the geometry of a given component. Sometimes, engineers use the pressure loss coefficient , PLC. It is noted K or ξ (pronounced “xi”). This coefficient characterizes pressure loss of a certain hydraulic system or a part of a hydraulic system.
