Pump shaft power calculation software! Water treatment industry! For design reference

Water pump shaft power calculation formula
This is the centrifugal pump: flow rate × head × 9.81 × medium specific gravity ÷ 3600 ÷ pump efficiency flow unit: cubic / hour, head unit: meter
P=2.73HQ/η, where H is the head in m, Q is the flow rate in m3/h, and η is the efficiency of the pump. P is the shaft power in KW. That is, the shaft power of the pump P=ρgQH/1000η (kw), where ρ=1000Kg/m3, g=9.8
The unit of specific gravity is Kg/m3, the unit of flow is m3/h, the unit of head is m, 1Kg=9.8 Newtons
Then P=specific gravity*flow*head*9.8 Newton/Kg
=Kg/m3*m3/h*m*9.8 Newton/Kg
=9.8 Newton*m/3600 seconds
=Newton*m/367 seconds
=watts/367
The above derivation is the origin of the unit. The above formula is the calculation of water power. The shaft power is divided by the efficiency.
