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. This dissipation, called head loss, is … See more After free falling through a height $${\displaystyle h}$$ in a vacuum from an initial velocity of 0, a mass will have reached a speed The term See more The distribution of hydraulic head through an aquifer determines where groundwater will flow. In a hydrostatic example (first figure), where the hydraulic head is constant, there is … See more • Borda–Carnot equation • Dynamic pressure • Minor losses in pipe flow • Total dynamic head • Stage (hydrology) See more Webh s = head before the impeller (m, in) h l = head loss from the surface to impeller - major and minor loss in the suction pipe (m, in) In an open tank the head at the surface can be expressed as: h 0 = p 0 / γ = p atm / γ (4b) For a closed pressurized tank the absolute static pressure inside the tank must be used.
