How to measure pump head
Web26 sep. 2024 · The submersible pump stage calculation tells you how many stages are required. You find it by dividing the total dynamic head (TDH) by the length of each stage. The TDH is the equal to the sum of the pumping level, head length, drop pipe friction loss and check value friction. The check valve is on top of the stages to let fluid rise to the ...

Velocity head can be calculated using the following formula: Where: g = 32.2 ft./sec. 2 V = liquid velocity in ft./sec.
WebHead is the height at which a pump can raise fluid up and is measured in metres or feet. We use it when specifying centrifugal pumps because their pumping characteristics tend to be independent of the fluid’s specific gravity, often referred to as relative density.
