The formula to calculate the Mean Effective Pressure is:
\[ \text{MEP} = \frac{\text{Work}}{\text{Displacement}} \]
Mean Effective Pressure is used to measure the performance of a combustion engine. Work is done when a force that is applied to an object moves that object. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Let's assume the following values:
Using the formula:
\[ \text{MEP} = \frac{250}{100} \approx 2.5 \, \text{Pascals} \]
The Mean Effective Pressure is approximately 2.5 Pascals.
