the ambient temperature is 320 K and 1 atm. At a certain operating point the pressure ratio across the compressor is 1.5
and compressor isentropic efficiency is 0.76. Based on the inlet manifold density of 1.6 kg/m3 at the exit of the
after-cooler the volumetric efficiency of the engine is 0.8. If the power required to drive the turbocharger
compressor is 5 kW at this operating point what is the engine speed? What is the amount of cooling rate (in
kW) for the after-cooler. (Take specific heat at constant pressure Cp=1 kJ/kg K and specific heat ratio k=1.4)
