2: diesel engine is fitted with a turbocharger, which comprises a radial compressor adial exhaust gas turbine. The air is drawn into the compressor at a pressure of 0.95 mperature of 15° (, and is delivered to the engine at a pressure of 2.0 bar. The engine is gravimetric air /fuel ratio of 18 : 1, and the exhaust leaves the engine at a temperature a pressure of 1.8 bar; the turbine exhausts at 1.05 bar. The isentropic efficiencies of th and turbine are 70 per cent and 80 per cent, respectively. Using the values P=1.01 kJ/kg K, air = 1.4 CP = 1.15 kJ/kg K, ex = 1.33 alculate the temperature of the air leaving the compressor. the temperature of the gases leaving the turbine ) the mechanical power loss in the turbocharger expressed as a percentage of the pow the turbine.
