So coming to your question, if you are running the pump for one hour then your motor would have consumed 1.49KW × 1hr = 1.49 KWh. 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 do you calculate power consumption of a motor per hour?
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 much energy will an electric motor of 1 horsepower consume in one second?
So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. Hence, 17.904 units of Power will be consumed by the 1 HP motor when run continuously for 24 hours.
How many units of electricity will be consumed if we run a 1 HP 3 phase motor for 24 hours?
Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW. So, the consumed units of electricity = Power in kW X numbers of hours of operation = 0.83 units (assuming the motor is running for an hour).
How much electricity does a water motor use?
A typical water pump’s wattage can vary between 250 watts to 1,100 watts. Take the wattage of the specific water pump and multiply it times how many hours a day it runs. Then, multiply it by how many days a year it runs, and divide by 1000.
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 1hp motor consume?
1 unit = 1 kilowat-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 much electricity does a 5 hp motor consume?
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 electricity does a 1 HP pool pump use?
Hi Joe, outside of the air conditioner, the pool pump is the largest energy consumer in the average pool-containing home. Pool pumps use up to 2,500 kWh per year to circulate and filter the water. The average monthly costs for a 1 HP pump running 8 hours per day in Florida is approximately $30*.
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.
How many kW is a 20 hp motor?
How do I calculate unit per hour?
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. So the reading on the electricity meter represents the actual electricity used.
How much does it cost to run a 100 hp motor?
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.
Are water pumps expensive to run?
Running costs for pumps
The very smallest in-pond filter/UV system (18w) — 8p per day. A 55watt UV lamp — 24p per day. A medium sized, 30cm wide, waterfall 1m high (60w) — 27p per day.

How much power does a pressure pump use?
Pumps draw power every time you turn on a tap. The energy consumption of pumps increases as the pumps get more powerful. For example, pumps rated at about 35L a minute use about 600 watts when they are pumping, while pumps rated at 45L a minute can consume about 800 watts.
