Air is initially at 260^(@)C and 700pa and occupied 0.028m^(3). The air is expanded at constant pressure to 0.084 m^(3). A polytropic process with n=1.5 is then carried out followed by a constant temperature process which complete the cycle. (a) sketch cycle in P-V. (b) find heat received and heat rejected in the cycle. (c ) efficiency of cycle.
