Question

An air compressor's inlet pressure and temperature conditions are 100 kPa and 290 K, respectively, the compressor pressurizes the ai to 500 kPa after which the air is cooled in an intercooler to 340 K by heat transfer to the ambient 290 K. Assume this first compressor stage has an isentropic efficiency of 85% and it is adiabatic. Using constant specific heat and find the compressor exit temperature and the specific entropy generation in the process. Assume constant CPo = 1.004 kJ/kg-K
