WebDec 27, 2024 · Velocity Head Calculation. In fluid mechanics, the head is a concept that correlates the energy in an incompressible liquid to the height of an equivalent static column of that liquid. The units for all the various forms of energy in Bernoulli’s equation can also be measured in distance units. Hence, these terms are sometimes introduced as ... 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 ...
