An engine has an energy input of 125 J, and 35 J of that energy is transformed into useful energy. What is the efficiency of the
xeze [42]

The efficiency of the engine at the given useful energy and input energy is 28%.

The given parameters:

  • <em>Input energy of the engine, = 125 J</em>
  • <em>Useful energy of the engine, 35 J</em>

The efficiency of the engine is defined as the ratio of the output energy (useful energy) to the input energy and it is calculated as follows;

efficiency\ = \frac{0ut put \ energy}{1nput \ energy} \times \ 100\%\\\\efficiency\ = \frac{35}{125} \times 100\%\\\\efficiency\ = 28 \ \%

Thus, the efficiency of the engine at the given useful energy and input energy is 28%.
