# How do you calculate units consumed by a motor?

Contents

Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.

## How many units does motor consume?

1 unit = 1 kilowatt-hour, i.e. when an electrical appliance consumes 1 killowat of Power for one hour . Here, we have a 1 HP motor. So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units.

## How many units does a 1 hp motor consume?

17904 Watt-hour is equal to 17904/1000 units and 1 HP for 24 hours is 746 24. When the 1 HP motor is running continuously for 24 hours, 17.904 units of Power will be consumed.

## How do you calculate power consumption?

The power consumed by the load is measured in watt. For example if a voltage across load is 10 V and load is drawing 2 A current then power consumed by load is 10*2=20 watt. Reactive power consumed by load = Square root of difference between squares of apparent power and active power.

## How much electricity does a 5 hp motor consume?

Output mechanical energy: 5 HP X 746 Watts = 3,730 Watts or 3.73 kW. As the output mechanical energy is the result of the motor performing at 80% efficiency, the power consumed by the 5 HP motor will be 3.73 kW X 100 ÷ 80= 4.66 kW.

## How much electricity does a 30 hp motor use?

Designed power capacity of a motor 30 HP,at 415 V, 3 phase power factor 0.8 (assumed). Full load current is , one HP is 745 w, 30 HP is 30 x 745 =23.35 kW, W = V x I x pf, 23.35 = 415 x I x 0.8, I = 23.35 divided by 415 x 0.8 = 67 amps.

## How much power does a 7.5 hp motor consume?

Let us assume that motor is operating at full load so it will consume 7.5 hp or 5.59 or 5.6 kW approx. Let us assume motor has efficiency of 90 %, motor at full load gives around 90 % efficiency, so the power input to motor is 5.6/0.9=6.22 kW. Energy consumption in 2 hrs = 6.22×2=12.44 KWh or 12.44 unit.

## What is meant by 1 unit?

1 Unit Electricity is the amount of electrical energy consumed by a load of 1 kW power rating in 1 hour. … 1 kWh (kilo watt hour) and 1 Unit are same. 1 kWh is the amount of energy consumption by 1 kW load in one hour. Therefore, 1 Unit = 1 kWh.

## How many kW is equal to 1 unit?

Energy/Electricity and its units

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.

## How much does a 1 hp motor cost?

Our 1 hp (standard) example UST1102 motor above will cost between \$1-\$5 per day, depending on what your power company charges per kWh, and on how many hours per day the pump is running, which changes within the season.

## How do you calculate the power consumption of a resistor?

Power can also be calculated using either P = IV or P=V2R P = V 2 R , where V is the voltage drop across the resistor (not the full voltage of the source). The same values will be obtained.

## How much power does a 100 hp motor use?

Data Logger information imported into a spreadsheet for analysis. This 100-horsepower centrifugal pump motor, if fully loaded, should be consuming nearly 80,000 watts (80 kW).

## How much power does a 2 hp motor use?

How many watts does a 2 HP motors have? If a 2 horse power motor is doing 2 horsepower of work then in the load about 1500 Watts of energy is used in the load.

## How much electricity does a 10 hp motor consume?

So a 10 hp motor will need 7680 watts when operating. In one hour the motor will consume 7.680 KWatt hours. If the units are charged at 10 cents each then then that equates to 10x 7.680 / 100 Dollars = 76.8 cents.
