What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
What is the efficiency of a generator that produces 80 kilowatts of electric energy and has electric and mechanical losses of 20 kilowatts?
power in equals power output plus power loss so input power for this question is 100 kw now use efficiency formula 100/80 times 100 to get 80% efficient
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
How can a machine's efficiency be calculated?
You use the definition of "efficiency": you divide output power by input power. Both of these, of course, need to be measured or calculated.
What must you know in order to calculate a machine's efficiency?
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
What is the formula to efficiency?
Efficiency = (output power/input power) x 100%
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
How do you calculate power if flowpressure and efficiency is given?

Formula for calculating efficiency of a power supply?
Efficiency = workout / workin * 100% how do I format this in the worksheet if the workout=KG what the work in will be?
What is the formula for rectification efficiency for full wave bridge rectifier?
It is defined as dc power delivered to the load to the ac input power from secondary transformer
What is the formula for calculating efficiency?
General formula for calculating efficiency is given by Efficiency = (output / input) * 100 It is denoted by greek letter Eta Efficiency cannot be more than 100%.
Efficiency is a comparison of?
Efficiency is output power divide by input power.
What is the efficiency of a generator that produces 80 kilowatts of electric energy and has electric and mechanical losses of 20 kilowatts?
power in equals power output plus power loss so input power for this question is 100 kw now use efficiency formula 100/80 times 100 to get 80% efficient
How is the efficiency of a machine calculated?
