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.
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.
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')
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.
stress is the ratio between the load and area
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.
the value 'n' of meter constant indicates that consumption of energy is n KWh.
P.F = Kwh/Kvarh
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.
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
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.

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.

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.
With 2.8 million people and an average Canadian load of 2.5 kW per person (one of the highest in the world), the average Toronto load is about 7 Gigawatts, which is about 160 GWh each day, or 160,000,000 kWh per day.
