Q2) A gas turbine plant operates on the ideal air standard Joule cycle. The min pressure and temperature are 1 bar and 335 K.

The max pressure and temperature are 8 bar and 1020 K.

(a) Sketch the processes on p-V and T-s diagrams. (2)

(b) Calculate EACH of the following:

(i) The temperature at all points; (5)

(ii) The heat supplied per kg; (2)

(iii) The network output per kg; (5)

(iv) The thermal efficiency. (2)

Note: For air C_P = 1.005 kJ/kg K and C_V = 0.718 kJ/kg K
