A supercharged engine with the following data:-
number of cylinder=6 engine capacity=5liter speed = 3500rbm volumetric efficiency=160%
the isentopic efficincy and mechanical efficincy of the subercharger are 95% and 87 respectivly it is designed to drive air to the cylinder at a certin temprture and 180 kpa pressure,if th volumetric efficincy before supercharging is 88% .
1) the engine power lost to run the supercharger
2) the increase in idicated power due to superchargine
