Hence the pump power calculation formula can be written as below pump power p kw q m 3 hr x ρ kg m 3 x g m 2 s x h m x p pa 3600000.

Pumps calculations formula. The same way pump power in horsepower formula can be written as pump power p hp q m 3 hr x ρ kg m 3 x g m 2 s x h m x p pa 2685600. P s kw p h kw η 3 where. Online pump calculator si units.

η efficiency of the pump between 0 to 100 formula 2. Also above pump power is required to lift the liquid to head meters. Q flow rate in m 3 sec.

P s kw shaft power kw η pump efficiency. H total developed head in meters density in kg m 3. 2 kinematic viscosity mm s absolute viscosity mpas fluid density kg m3.

P in watt here. P in kw here. Q flow rate in m 3 hr.

The shaft power the power required transferred from the motor to the shaft of the pump depends on the efficiency of the pump and can be calculated as. G gravitational constant 9 81 m sec 2.
