Consider the turbocharger of an internal combustion engine. The exhaust gases enter the turbine at 450 °C at a rate of 0.02 kg/s and leave at 400 °C. Air enters the compressor at 70 °C 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 turbine work is lost during its transmission to the compressor). Using air properties for the exhaust...
