ip      = indicated power (kW)

bp     = Break Powder (kW)

Pim     = indicated mean effective pressure (N/m2) Pbm = Break mean effective Pressure (N/m2)

L        = length of stroke

A       = area of piston (m2)

N       = number of power strokes 

= rpm for 2 stroke engines = rpm/2 for 4-stroke

K       = no. of cylinder.
