The head of a pump is a measure of the energy imparted to the fluid by the pump, usually expressed in units of feet (ft) or meters (m) of fluid. It represents the increase in pressure (or more accurately, the increase in pressure energy) that the pump provides to overcome resistance in the system, such as friction losses in pipes and rises in elevation. booster pump head calculation xls

The calculation of the Total Dynamic Head (TDH) for a booster pump is essential to ensure the system delivers the required pressure and flow to the most remote fixture. | | Minor losses | Some sheets allow
