Therefore, the power consumed by a 5 HP motor performing at 80% efficiency will be: 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 does it cost to run a 5hp electric motor?

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 do I convert HP to kwh?

Multiply the number of horsepower by the time the power is exerted. For example, if you have a 20-horsepower motor running for three hours, you would multiply 20 by 3 to get 60 horsepower-hours. Multiply the number of horsepower-hours by 0.7457 kilowatts per horsepower-hour to convert to kilowatt-hours.

## How do you calculate kwh of a motor?

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. Electricity costs are based on kilowatts (kW), so divide watts by 1000 to convert to kilowatts (20,760 wats/1000 = 20.76 kW). Record the time the motor is in operation.

## How many kwh does a 2 hp motor use?

If it is for 2 hours, then 1.49KW × 2hr = 2.98 KWh. This is how the energy( KWh)consumed by the motor is determined.

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

Expect actual operating costs to vary. For example, a 460-volt, three-phase, standard efficiency 100 HP motor operating under full load for 8,760 hours per year will probably cost just over $48,000 per year to operate at an electric rate of $0.10 per kWh.

## 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.

## Which is greater HP or kW?

Obviously, a kilowatt is 1,000 watts. … To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.

## How many kilowatts does a 1 hp motor used?

0.7457 kilowatts

## How much kVA is 1 HP?

## How do I calculate kWh?

To convert the power in watts to kilowatt-hours, multiply 100 watts by 1 hour, then divide by 1,000 to find the energy usage in kWh. If electricity costs $0.12 per kWh, then a 100 watt light bulb will cost 1.2 cents per hour that it’s on.

## What is the formula for power consumption?

The first step in calculating your energy consumption is to figure out how many watts each device uses per day. Just multiply your appliance’s wattage by the number of hours you use it in a day. This will give you the number of watt-hours consumed each day.

## How do I calculate my electricity meter reading?

Choose clean energy and savings, now.

- Current meter reading – Meter reading reported from last month’s bill = Total kWh used since last reading.
- Total kWh used since last reading x Charge per kWh = Total energy charge.
- Total energy charge + Fixed monthly fees = Final bill.

## How much electricity does a 1 hp pump use?

A 1 hp sump pump SHOULD draw about 750 watts running and about 15-1800 starting. Also, how many watts does a water pump use? A typical water pump’s wattage can vary between 250 watts to 1,100 watts.

## How many kWh does a water pump use?

Well pumps use a huge amount of energy every time they start up. Well pumps should be sized by a professional. It is not uncommon for people to have 3/4 hp pumps installed in their wells equaling 30 minutes of pumping per day or 350 kWh/yr, while a ½ hp pump, which uses only 240 kWh/yr, would be sufficient.
