Unit consumed = Power in kW X numbers of hours of operation. = 59.76 units. Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded. In actual, motor load will be less than full load and units consumed will be less accordingly.
How many watts is a 3 phase motor?
Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).
How much electricity does a 2 hp motor consume?
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 watts does a 1 hp electric motor use?
|2 hp||1491.399744 W||1491 Watts|
|3 hp||2237.099616 W||2237 Watts|
|4 hp||2982.799488 W||2983 Watts|
How do you calculate the cost of electricity for a 3 phase motor?
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 electricity does a 1 HP pool pump use?
Our 1 hp example pump uses 1.75 Kw per hour; whereas a 2 hp motor of the same type (UST1202) would draw 2.4 Kw per hour. That’s around 24 kWh per day, or around 720 kWh per month, just running only 10 hors per day. During the heat of the summer, many pumps need to run longer to maintain clear water.
How much electricity is consumed if I run a 1 hp motor in 3 phase for 1 hour?
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 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 electricity does a 5 hp motor use?
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 many kW is a 5hp motor?
Hp to kW Conversion Table
|1 hp||0.745699872 kW||1 kW|
|5 hp||3.72849936 kW||4 kW|
|10 hp||7.45699872 kW||7 kW|
|15 hp||11.18549808 kW||11 kW|
How much electricity does water motor consume?
To give you a rough estimate the average rated power of water pump is from 250 watts to 1500 watts. Smaller the water pump, less is the wattage, less is the power consumption, hence low is the discharge and head.
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 much does 100w cost per month?
Electricity usage is calculated in kilowatt-hours. A kilowatt-hour is 1,000 watts used for one hour.
