Online Pumping calculator helps to calculate the horsepower of prime mover from user the inputs.
How to Calculate Prime Mover HP for Motor?
Assumes High Slip (NEMA D) Motor. BPD = 217 @ 1--% Pump Efficiency, Depth = 5600 feet, Pump Setting.
HP = [217 x 5600] / 56000 = 21.7 (Use 25 HP motor)
Formula:
HP = [BPD × Depth] ÷ Motor Type
where,BPD = Barrels per Day
Depth = Pump Setting (feet)
