An air compressor operates at steady state with air entering at p1 5 1 bar, T1 5 178C and exiting at p2 5 5 bar. The air undergoes a polytropic process for which the compressor work input is 162.2 kJ per kg of air flowing. Determine (a) the temperature of the air at the compressor exit, in 8C, and (b) the heat transfer, in kJ per kg of air flowing. (c) Sketch the process on p-y and T-s diagrams and associate areas on the diagrams with work and heat transfer, respectively. Assume the ideal gas model for air and neglect changes in kinetic and potential energy.
