# Friction Mean Effective Pressure Calculation

FMEP stands for Friction Mean Effective Pressure. The difference between Indicated Mean Effective Pressure (IMEP) and Brake Mean Effective Pressure (BMEP) is Friction Mean Effective Pressure (FMEP). It is used as an indicator of the mean effective pressure lost to friction. Friction mean effective pressure calculation requires accurate measurement of cylinder pressure and dynamometer brake torque. Use our online FMEP calculator to calculate the difference between IMEP and BMEP which is FMEP.

FMEP stands for Friction Mean Effective Pressure. The difference between Indicated Mean Effective Pressure (IMEP) and Brake Mean Effective Pressure (BMEP) is Friction Mean Effective Pressure (FMEP). It is used as an indicator of the mean effective pressure lost to friction. Friction mean effective pressure calculation requires accurate measurement of cylinder pressure and dynamometer brake torque. Use our online FMEP calculator to calculate the difference between IMEP and BMEP which is FMEP.

#### Formula:

FMEP = IMEP - BMEP Where, FMEP = Friction Mean Effective Pressure IMEP = Indicated Mean Effective Pressure BMEP = Brake Mean Effective Pressure

### Example:

Calculate Friction mean effective pressure if BMEP is 40 Pa and IMEP is 60 Pa?.

FMEP = 60 - 40
= 20 Pa
