WebPump Power P (kW) = q (m3/hr) x ρ (kg/m3) x g (m2/s) x h (m) x p (Pa) / 3600000. The same way pump power in horsepower formula can be written as, Pump Power P (HP) = … WebThe theoretical pump power can be calculated as. P h(kW) = (1 m 3 /h) (1000 kg/m 3) (9.81 m/s 2) (10 m) / (3.6 10 6) = 0.027 kW. Example - Power pumping Water, Imperial Units. 600 gpm of water is pumped a head of 110 ft.

WebJun 4, 2024 · 1 I used to calculate the power needed by a pump using Bernoulli equation, W = ( p 2 − p 1) + 1 2 ρ ( u 2 2 − u 1 2) + g ρ ( h 2 − h 1) + R where ρ is fluid density (and assuming it is constant), subscript 1 is inlet, 2 is outlet, p is pressure, u is speed, g is acceleration of gravity, h is and R are pressure drops (see EDIT2 ). WebLearning Objectives. Upon completion, learners should be able to: 1. Calculate pump input power from torque and speed measurements 2. Calculate pump input power from electrical input power measured to the motor 3. Calculate hydraulic power (i.e., water horsepower), and the important variables 4. Calculate bowl, pump, motor, and overall efficiency. frame shop at waynesville mo
