Air enters the turbocharger compressor (see Fig. P8.51) of an automotive engine at 100 kPa, 30°C and exits at 200 kPa. The air is cooled by 50°C in an intercooler before entering the engine. The isentropic efficiency of the compressor is 75%. Determine the temperature of the air entering the engine and the irreversibility of the compressioncooling process.
