Velocity Head

Velocity head is the amount of head or energy required to maintain a stated velocity in the suction and discharge lines. The design of most pumps makes the total velocity head for the pumping system zero.

Note: Velocity head only changes from one point to another on a pipeline if the diameter of the pipe changes.

Velocity head and total velocity head are determined by:

Total Velocity Head (ft) = Velocity Head Discharge (ft)

- Velocity Head Suction (ft)
