Pressure head is a component of hydraulic head, in which it is combined with elevation head. When considering dynamic (flowing) systems, there is a third term needed: velocity head. Thus, the three terms of velocity head, elevation head, and pressure head appear in the head equation derived from the Bernoulli equation for incompressible fluids: 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 fluid, plus … See more Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum.

WebPressure can be measured either as part of a scale (e.g. bar, pascals, psi) or in terms of the height of a fluid (e.g. metres of water). The higher the height of liquid, the greater the pressure it exerts at it’s base. Pressure gauges typically incorporate scaled measurements whereas pump performance is measured by its head – ie what height ... Webpressure head - p / γ; velocity head - v 2 / 2 g; elevation head - h; is constant along a stream line. This constant can be called the total head - H. The total head in a flow can be determined by measuring the stagnation …
