I assume you are asking how much energy a 5-hp motor will consume in one hour?
The first thing to understand that a motor is rated according its output power which, in North America, is expressed in horsepower and, elsewhere, in watts. So, the output power of your motor is 5 hp, which is equivalent to 5 x 746 = 3730 W.
Next, you need to find out its full-load efficiency. You then need to divide the output power by the efficiency to determine its input power -remember, input power is always higher than the output power.
Once you have found out its input power, convert that into kilowatts and multiply it by one (hour) to determine the energy used in kilowatt hours.
It depends on the motor's design. One motor I recall could only be started three times in an hour, and then only in exigent circumstances. Others are not so limited. It comes down to the thermal load that is placed on the motor as a result of startup.
Electricity consumption is measured in Kilowatt hours, this is one unit of electric consumption and charged according to your supplier. You have to know how many watts your devices consume. This is sometimes written on the ID tag or plate, or you can use a meter in line. Multiply this wattage number by the hours it is switched on and this will tell you how much it has consumed. e.g. A toaster may consume 1000Watts = 1Kw, if you ran it continuously for an hour it would consume 1 unit of electricity. Toasters don't run for more than a few minutes, so would use less than 1 unit per operation. 3 mins = 0.05hrs Therefore = 0.05 of a unit. A 100W light bulb would consume 1 unit in ten hours. 100W = 0.1 KW. = one tenth of a kilowatt, so ten times this would equal 1 Kw/h, Therefore ten hours.
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
A unit, short for 'Board of Trade unit', is used to measure energy and is exactly equivalent to a kilowatt hour.When a motor is described as being rated at, say, 0.75 horsepower, what is being described is its output power or the rate at which it is supplying energy to its mechanical load. So, it's necessary to determine what the input power (which is greater than its output power) is and, to do this, you need to know its efficiency.If we assume that the efficiency of the motor is, say, 85% at its rated output, then the input power will be (0.75 x 746) / 0.85 = 658 watts. The amount of energy supplied to the motor, therefore, will be (658/1000) x 1 = 0.658 kilowatt hours.
That you were able to ask this question. Without electricity, we wouldn't have many of the things we have now. A LOT of stuff use electricity to work.
Depends on the size of the engine. 300 HP = 80 L an hour
1500 watt hours
You need to find out the power of the motor in kW or HP before that question can be answered.
About 50,000 to 65,000 Gallons
too many About 2 million
1000
1,000 watts
Many, but not all, have an electric motor as to drive them.
For calculation purposes one horse power is equal to 746 watts. So a 1.5 HP motor will be rated at 1.5 x 746 = 1119 watts or 1.119 kW. To calculate the cost of operating the motor your utility cost per kilowatt hour has to be stated. Take this cost and multiply it by the 1.119 to obtain your hourly cost of operating the motor.
1.1 kW-hours
7.5 kW equates to 25,591 BTU/hour.
