useful energy output of an engine is 1.75 x 10^3kJ and the total mechanical engery input is 4.00 x 10^3kJ. The efficiency of engine is
To calculate the efficiency of the engine, we can use the formula:
Efficiency = (Useful energy output / Total mechanical energy input) * 100
Given the following values:
Useful energy output = 1.75 x 10^3 kJ
Total mechanical energy input = 4.00 x 10^3 kJ
Plugging these values into the formula:
Efficiency = (1.75 x 10^3 kJ / 4.00 x 10^3 kJ) * 100
Simplifying the equation:
Efficiency = (0.4375) * 100
Calculating the product:
Efficiency = 43.75%
Therefore, the efficiency of the engine is 43.75%.
