Mean Effective Pressure Formula. p me =(2π T × nr )/ V d For an engine with multiple cylinders we have to take into account the total volumetric capacity Here nc will be the number of cylinders so the Mean effective pressure for the multiple cylinder engines is p me =(2π T × nr )/nc V d.

p me = (2 π n r T) / V d (6) As you can see from expression (6) the mean effective pressure is not influenced by the engine speed Also since the torque is divided by the engine capacity the mean effective pressure parameter can be used to compare internal combustion engines of different displacements.
What is Mean Effective Pressure MEP Otto cycle Definition
p = WV−1 Dimension L − 1 M T − 2 {\displaystyle {\mathsf {L}}^ {1} {\mathsf {M}} {\mathsf {T}}^ {2}} The mean effective pressure is a quantity relating to the operation of a reciprocating engine and is a valuable measure of an engine's capacity to do work that is independent of engine displacement Common symbols pIn SI base units 1 ⋅−1⋅−2Derivations from other quantities p = −1SI unit (Pa).
What is Mean Effective Pressure? IMEP, BMEP, FMEP
Mean Effective Pressure can be calculated using the following formula MEP = 1508 x (Torque / CID) CID is the cubicinch displacement of the engine under scrutiny.

Mean effective pressure Wikipedia
For example the net indicated mean effective pressure known as IMEP n is equal to the mean effective pressure calculated from incylinder pressure (there must be this measurement) over the complete engine cycle Note that it is 720° for a fourstroke engine and 360° for a twostroke engine.
