WebOct 22, 2024 · Head loss is potential energy converted into kinetic energy. Head loss is defined as the pressure loss due to viscous effects over a certain distance of pipe for an incompressible fluid, also including the additional losses accrued by fixtures etc. Head loss cannot be avoided in real fluids, and its importance is relative to the value of the total head.
