2.3 Components of Hydraulic Head

WebElevation Head In general, the hydraulic head, or total head, is a measure of fluid’s potential at the measurement point. It can be used to determine a hydraulic gradient between two or more points. In fluid dynamics, the head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid.
