A mass of air is initially at 2600C and 700Kpa and occupies 0.
The air is expanded at constant pressure to 0.
A polytropic process with n = 1.
5 is then carried out, following by constant temperature process all process are reversible (a) Sketch the cycle pV& Ts planes.
(b) Find the heat received and rejected in the cycle.
(c) Find the efficiency of cycle.
