If the motor is fully loaded, it will provide output power of 3HP = (3 X 0.746) kW = 2.24 kW.
Electrical input power = output power / (Efficiency /100).
Assuming 90 % efficiency, input power = 2.24 kW / (90/100)
= 2.49 kW
Unit consumed = Power in kW X numbers of hours of operation.
= 2.49 X 24 units
= 59.76 units.
Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded
