What is the efficiency formula?

Updated: 4/28/2022

Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.

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.

What is the Otto cycle efficiency formula and how can it be used to calculate the efficiency of an engine?

The Otto cycle efficiency formula is given by: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio of the working fluid. This formula can be used to calculate the efficiency of an engine by plugging in the compression ratio and specific heat ratio values. The higher the efficiency value, the more effectively the engine converts fuel into useful work.

What is the efficiency of the Otto cycle formula and how can it be optimized for maximum efficiency?

The efficiency of the Otto cycle is given by the formula: Efficiency 1 - (1 / compression ratio)(-1), where is the specific heat ratio. To optimize the efficiency of the Otto cycle for maximum efficiency, you can increase the compression ratio, improve combustion efficiency, reduce heat losses, and use higher octane fuel.
