WebDec 17, 2011 · NPSHA = Ha +/- Hz - Hf + Hv - Hvp. Where: Ha is the atmospheric or absolute pressure. Hz is the vertical distance from the surface of the water to the pump centerline. Hf is the friction formed in the suction piping. Hv is the velocity head at the pump's suction. Hvp is the vapor pressure of the water at its ambient temperature.

Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a hydraulic gradient between two or more points. See more Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or … See more 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 … See more The hydraulic gradient is a vector gradient between two or more hydraulic head measurements over the length of the flow path. For groundwater, it is also called the Darcy slope, since … See more In any real moving fluid, energy is dissipated due to friction; turbulence dissipates even more energy for high Reynolds number flows.
