Energy Transfer Efficiency Calculator

Formula

The formula to calculate the Energy Transfer Efficiency (η) is:

\[ \eta = \left( \frac{E_{u}}{E_{t}} \right) \times 100 \]

Where:

Energy Transfer Efficiency (η): A measure of how effectively energy is converted from one form to another in a system.
Useful Energy Output (E_u): The amount of energy that is effectively used for the intended purpose.
Total Energy Input (E_t): The total amount of energy supplied to the system.
Significance: High energy transfer efficiency means more input energy is used effectively, while lower efficiency indicates more energy is lost to waste.

Let's say the useful energy output (E_u) is 400 Joules and the total energy input (E_t) is 500 Joules. Using the formula:

\[ \eta = \left( \frac{400}{500} \right) \times 100 = 80 \]

So, the Energy Transfer Efficiency (η) is 80%.
