what is value of energy does a 5 hp motor deliver in 2 hours
Answers
Step-by-step explanation:
How much electricity is consumed by a 5 h.p. electric motor per hour?
1 Horsepower is equal to 745.7 watts of electrical power, so in theory a 5HP motor operating at 100% efficiency will consume about 3.728kW of power. In one hour, it will use 3728.5 kilowatt-hours.
Of course, no motor is 100% efficiency, so the motor will actually consume somewhat more power than this. How much more will depend on the motor, how efficient it is, and where it is on its power/torque curve. In practice, the actual power consumption could be twice the mechanical power output, so it could be consuming over 7 kilowatt-hours.
Additionally, the power consumption will depend on the actual mechanical load. Calling a motor a ‘5HP’ motor generally means that it is a motor rated for a constant power output of 5HP. If you’re only using it to drive a 1HP load, the power consumed will also be a lot less than if it was driving a 5Hp load.
