(b) Air at 1.013 bar and 28°C with a specific volume of 0.98m³/kg is reversibly and adiabatically compressed through a volume ratio of 7:1. The work done during the compression is -6.5 kJ and the final temperature of the gas is 388°C. Calculate the values of (i) final pressure, (ii) Cp, (iii) C., and (iv) mass of the air. Take y = 1.4.
