Calculate Brake Mean Effective Pressure (BMEP)



Formula

The formula to calculate the brake mean effective pressure (BMEP) is:

\[ BMEP = 150.8 \times \frac{T}{D} \]

Where:

What is BMEP?

BMEP, which stands for brake mean effective pressure, is a measure of the total pressure that if applied to the pistons of an engine through an entire stroke, would produce the power output of the engine.

Example Calculation

Consider an example where:

Using the formula to calculate the BMEP:

\[ BMEP = 150.8 \times \frac{300}{400} = 113.1 \text{ psi} \]

This means that the brake mean effective pressure for this example is 113.1 psi.
