Q/ The following data are recorded for supercharged engine: Engine capacity =5 liter, Speed =3500 , Volumetric efficiency =160%. Isentropic efficiency =95% Mechanical efficiency of the supercharger =87% It is desired to deliver air to the cylinder at the certain temperature and 180kPa pressure. If the volumetric efficiency betore supercharging is 88%, calculate: a) Engine power lost to run the supercharging. b) The increase in indicated power due to positive pump loop. Take: Cp of air =1.005kJ/kg.K, R=0.287kJ/kg.K Ambient conditions (296 K \& 100kPa)
