a) Explanation Write the expression for the quasi equilibrium boundary work. W b = ∫ 1 2 P d V W b = P 1 V 1 ln V 2 V 1 (I) Here, pressure at state 1 is P 1 , initial volume is V 1 , and final volume is V 2 . Write the expression for the workdone against the atmospheric pressure. W s u r r = P 0 ( V 2 − V 1 ) (II) Here, atmospheric pressure is P 0 . Write the expression for the use full work. W u = W b − W s u r r (III) Write the expression for the energy balance of the system Q i n − Q b , o u t = Δ U Q i n = Q b , o u t Here, heat transfer to the system is Q i n , heat transfer from the system to surrounding is Q b , o u t , and change in internal energy is Δ U . Conclusion: Substitute 350 kPa for P 1 , 0 .01 m 3 for V 1 , 0.02 m 3 for V 2 , and 0.01 m 3 for V 1 in equation (I) b) To determine The exergy destruction during the process c) To determine The exergy destruction during the process.
