What is formula for kwh in three phase power?
Multiply the power of the load [1.732 x UL IL x power factor], expressed in kilowatts, by the operating time, expressed in hours. This is only practical for a constant load.
How do you calculate load factor of gear box?
K Factor Also called an Overhung Load Factor. A constant used to modify the overhung load rating of a gearbox based on the type of load applied on the shaft. Use the K factor either to increase the calculated overhung load, or to reduce the gearbox overhung load rating.
How do you calculate kwh in three phase?
In exactly the same way as you do so for a single-phase load. It's the product of the power of the load, expressed in kilowatts, and the during of operation, expressed in hours. (And the symbol of kilowatt hours is 'kW.h', not 'kwh')
How many kWh in 750 kW?
KWH = KW times hours If you run a 750 KW load (lights, motors, so forth) for 1 hour, you have 750 KWH. If you run it for 1/2 hour, 750 KW X .5 hours = 375 KWH. If you run it for 5 hours, 750 KW X 5 = you do the math.
How do you calculate half load speed of induction motor if given full load peed?
To calculate the half load speed of an induction motor, you first need to understand that the synchronous speed remains constant regardless of the load. The full load speed is generally slightly less than the synchronous speed due to slip. To estimate the half load speed, you can use the slip at full load and apply it to the synchronous speed, recognizing that slip may change slightly at half load. However, for a rough estimate, you can assume half load speed is close to the full load speed, as the change in speed due to varying loads is minimal in induction motors.
How do you work out total cost of 35kwh to cost per kwh?
To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
What is the significance of energy meter constant?
the value 'n' of meter constant indicates that consumption of energy is n KWh.
How you calculate import Kvarh in percentage?
P.F = Kwh/Kvarh
How do you calculate 3 phase kWh to amps when 8000 kWh monthly average is used?
It depends on the voltage. Please restate the question and provide the voltage. In general, however, simply divide total power by KV to get KA. Remember the KWH is an integral, so you need to back calculate KW. If the month is a 30 day month, then KW is KWH / 30 / 1440. Then, if the load is star, simply divide by three; if the load is delta, divide by three and multiply by 1.732, the square root of 3. Example: 480 three phase running star. 8000 / 30 / 1440 is 185 amperes. 185 divided by 3 is 62 amperes per phase. For delta, that becomes 107 amperes.
What is the average cost of an electric bill for a house?
There are two main factor to calculate an electric bill of a house. 1. Tariff per KWH 2. The load of House in terms of KW If you have average consumption of your house then you can calculate easily your house bill. For example you have average use of 100 KWH per month and tariff is $2.00 for 1 KWH then you average bill will be $400 per month. But again it depends the home appliances being used in your house and tariff defines by the electric company.
How much per hour would an 800kW cost to use?
To calculate the hourly cost of using an 800 kW load, you would need to know the cost of electricity per kilowatt-hour (kWh). For example, if the electricity rate is $0.10 per kWh, the hourly cost would be 800 kW × $0.10/kWh = $80. Therefore, the cost to use an 800 kW load for one hour would be $80, assuming that rate. Adjust the calculation based on your local electricity rates for a more accurate figure.
When the load is at a constant position on the lever arm how can you make it easier to lift the load?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate the kWh consumed by a 3-phase motor, you'll need to know both the power factor and operating hours. The formula is: kWh = (√3 x Volts x Amps x Power Factor x Hours) / 1,000. Without the power factor and hours of operation, a precise kWh calculation cannot be provided using just voltage and current.

What is the cost of operating a 3.00 W electric clock for a year if the cost of electricity is .09 kWh?
To calculate the cost of operating the electric clock for a year, first convert the power rating to kWh: 3.00 W = 0.003 kW. Then calculate the total energy consumed in a year: 0.003 kW * 24 hours/day * 365 days = 26.28 kWh. Finally, multiply the total energy consumed by the cost per kWh: 26.28 kWh * $0.09/kWh = $2.36 for operating the electric clock for a year.
