How do you calculate the Hydraulic power, shaft power and motor power of a centrifugal pumps?

Inputs needed:

Hydraulic power,

Is also called useful power or water horsepower, is the actual power imparted to the fluid by the pump. It depends on three primary parameters:

Phyd=ρ×g×Q×H

Shaft Power: Is calculated as;

Pshaft=Phyd / ηp (Pump efficiency)

Motor Input Power (Electrical Power Consumption)

Pmotor=Pshaft / ηm (Motor efficiency)

Flue gas flow in ESP, Q = 61920 m3/hr / 3600 = 17.2 m3/sec

Total collecting area A= 131.9 X 17.2 =2268.68 m2

Migration velocity of dust particles, V = 5.46/100 = 0.0546 m/sec

Efficiency of ESP = 1–eˆ (-AV/Q) X 100

= 1– eˆ (-2268.68 X 0.0546/17.2) X 100

ηESP = 99.92%
