It is important to calculate this accurately in order to determine the correct sizing and scale of pumping equipment for your needs.
Water supply pump head calculation.
Apply the water head pressure calculation to a head loss computation.
If you have to pump water to the fifth floor of an apartment building and want to have 45 psi water pressure available to the occupants you can determine the minimum pump pressure required at ground level.
Net positive suction head available 22 13 m.
Download links chilled water pipe sizing and design calculation.
It s necessary to calculate head flow rate and useful power of centrifugal pump pumping low viscosity fluid with density of 1 020 kg m 3 from tank with overpressure 1 2 bar to tank with overpressure 2 5 bar along given pipeline with pipe diameter 20 cm.
The water is at20c has a density of998 kg m3 a vapour pressure of0 023 bara and a viscosity of1cp.
Treatment works for treatment before the water goes into the supply network.
It is comprised of two parts.

Enter all the values you found into this formula to find the water horsepower for your project.
We ll assume that the pump efficiency is70.
Pump total differential head 134 8 m.
The ideal hydraulic power to drive a pump depends on.
The vertical rise and friction loss.
The differential height either it is the static lift from one height to an other or the total head loss component of the system and can be calculated like.
Click the update button to calculate total losses for the system.
The water horsepower or minimum power required to run the pump equals where tdh is the total dynamic head in feet q is the flow rate in gpm and sg is the specific gravity 1 for water.
Pump flow rate 30 m3 hr.
