Question

Consider the turbocharger of an internal combustion engine. the exhaust gases enter the turbine at 450oc @ 0.02 kg/s and leave at 400oc. air enters the compressor at 70oc and 95 kpa at a rate of 0.018 kg/s and leaves at 135 kpa. the mechanical efficiency between the turbine and the compressor is 95 percent (5 percent of the turbine work is lost during the transmission to the compressor) using air properties for the exhaust gases, determine

a.the air temperature at the compressor exit and

b.the isentropic efficiency of the compressor.
