(a) (i) Deduce the efficiency of Carnot cycle in terms of temperature from its p-Vdiagram. (4) (ii).

a) (i) Deduce the efficiency of Carnot cycle in terms of temperature from its p-Vdiagram. (4) (ii) Air is compressed from 100 kPa and 300 K to 5 bar isothermally and then it receives heat at constant pressure. It is finally returns to its initial condition by a constant volume path. Plot the Cycle on p-V and T-s diagram and calculate the net heat and work transfer. (2 + 2 + 4 + 4)
