Air enters the turbocharger compressor of an automotive engine at 14.7 lbf/in.2, 90 F and exits at 25 lbf/in.2, as shown in Fig. P8.51. The air is cooled by 90 F 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 compression-cooling process.
