Pump Power

Power for pump :-

P= Q U g H(J\N)....... Watt

Q: Capacity of fluild m3\s

U : Denisty Of Fluid kg\m3

G : Garvity earth 9.18 m\s2

H : Total Head ( Include any dynamic , static , Friction Losses , Net Pressure suction head) m

That is power in watt

power in KW We duplicate in 1000

Powe in HP = 0.736 KW

That is For Pump Circulating pumps calculates

and check for more accuracy

The power needed for any fluid mover can be found by multiplying the pressure rise by the volumetric flowrate, and dividing by the efficiency.

Rules of thumb like the above can give a good first stab at it. However, it's the efficiency bit that is a problem, so reference to manufacturer's published pump performance curves is the usual way out.
