Q17. A volume of 0.05 m³ of a perfect gas for which R = 0.297 kJ/kgK and C_p = 1.04 kJ/kg K is compressed reversibly in a cylinder according to the law pV^l.33 = constant and then cooled at constant pressure. The initial temperature is 27℃ and the final pressure is 8.5 times the initial pressure. The final volume is 0.007 m³.

(a) Sketch the processes on p-V and T-S diagrams, (4)

(b) Determine EACH of the following:

(i) the temperature after compression; (2)

(ii) the final temperature; (2)

(iii) the net heat transfer per kg; (5)

(iv) the net change in specific entropy. (3)
