Brake Mean Effective Power in Engine Dynamics Formulas

Brake Mean Effective Power is defined as the average pressure which, if imposed on the pistons uniformly from the top to the bottom of each power stroke, would produce the measured power output. And is denoted by P_b. Brake Mean Effective Power is usually measured using the Pascal for Pressure. Note that the value of Brake Mean Effective Power is always positive.
