Q8. A perfect gas is heated at constant pressure in a cylinder and then expands reversibly according to the law pV^1.32 = C.

The initial pressure and temperature are 10 bar 527°C respectively.

The final pressure is 1.0 bar and the final volume is twenty times the initial volume.

(a) Sketch the p-V and T-s diagrams.

(b) Calculate EACH of the following:

(i) The temperature after heating

(ii) The final temperature

(iii) The net heat transfer per kg of gas

(iv) The net change in specific entropy during the constant pressure process.

Note: For the gas γ = 1.67, C_p = 5.179 kJ/kgK; R =2.078 kJ/kgK
