What is the formula for indicated mean effective pressure?

a) Pi = \(\frac{(Area \, of \, indicator \, diagram)}{Length \, of \, indicator \, diagram \, * \, spring \, scale \, index} \)
b) Pi = \(\frac{(Length\, of \, indicator \, diagram \, * \, spring\, scale \,index)}{Area\, of \,indicator \, diagram} \)
c) Pi = \(\frac{Length \, of \, indicator \, diagram}{Area \,of \,indicator\, diagram \, * \, spring \, scale \, index} \)
d) Pi = \(\frac{Spring \, scale \, index}{Area \, of \, indicator \, diagram \, * \, Length \, of \, indicator \, diagram} \)

Answer: a
Explanation: Indicated mean effective pressure is the algebraic sum of the mean pressures acting on the piston during each stroke over one complete cycle. It is measured through indicator diagram drawn with the help of an engine indicator.
