Head fluid dynamics
In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the energy associated with the movement of the fluid, plus energy from static pressure in the … See more Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum.
