How much electricity will a 15 Hp motor consume in 1 hour?

Answer 1

1 hp equals 746 watts. The question confuses energy and power.

Answer

You do not 'use' power. Power is the rate at which you 'use' energy. Your question is rather like asking, "How many miles per hour do you do in one hour?"

Answer 2

If i use 1 hp 3 phase water motor for 1 hour how much power it consumes

Answer

By 'electricity consumed', you presumably mean 'energy consumed' ('electricity' is not a quantity, so you cannot measure it!). As 1 horsepower represents the outputpower, you will need to know the efficiency at that load in order to determine its input power. Assuming the load is constant, you will then need to multiply the input power, expressed in kilowatts, by the length of time it is operating, expressed in hours.

Answer 3

The number of watts is the same in one second, one hour, or one century. A watt is a unit of power, not a unit of energy. 1 hp = 746 watts.

In one hour a 746-watt appliance would use 746 watt-hours or 0.746 kilowatt-hours of energy.

Answer 4

One horsepower is equal to 746 watts. 15 horsepower is equal to 15 x 746 = 11190 watts.

==

You will need to know the machine's efficiency, because the input power to the machine is always higher than its output power. Once you've figured out the input power you will need to multiply this figure, expressed in kilowatts, by the time the motor is running, expressed in hours. This will give you the amount of energy (which I assume is what you mean by 'electricity') consumed over that period in kilowatt hours. Your electricity supply company will be able to tell you how much they charge, per kilowatt hour, for energy, from which you will be able to calculate the running costs.

Answer 5

A 1-hp motor draws about 900 watts, so in an hour it consumes about 0.9 units of energy. Theoretically 1 hp is 746 watts but you have to allow extra for heat lost as the motor warms up.

Answer 6

On a 240 v system it uses about 900 watts all the time it's running. In one hour it uses 900 watt-hours (0.9 kilowatt-hour).
