18.13 A rotary compressor is used to supercharge a petrol engine. The static pressure ratio across the rotor is 2.5:1. Static inlet pressure and temperature are 0.6 bar and 5°C, respectively. The air-fuel ratio is 13:1 and the engine consumes 0.04 kg fuel/s. For the air-fuel mixture take y = 1.39 and 1.005 kJ/kg K. The isentropic efficiency of the compressor is 84%. Estimate the power required to drive the compressor. Taking the exit velocity from the compressor as 120 m/s and assuming that the mixture is adiabatically brought to rest in the engine cylinders, estimate the stagnation temperature and pressure of the mixture at the beginning of the compression stroke in the engine cylinder. с
