Air in a tank in the power plant undergoes a polytropic compression from the pressure 1 bar and the temperature 22 ° C to a pressure of 5 bar. Calculate how much work is required for the compression as well heat transport per kg of air if: 1. n= 1; (Answers- 127 kJ/kg and 32 kJ/kg) 2. n= k; (Answer- 95 kJ/ kg and 0,when n = k it gives an adiabatic process.) 3. For the case when n = k, calculate the final Answer: 468 K (2r
