Transcribed Image Text:

Air at state 1 at 5 bar and 1000 K having 0.01 kg mass is expanded in a reciprocating cylinder to state 2 at a pressure of 1 bar and temperature of 600 K. Atmospheric temperature and pressure are 300 K and 1 bar, respectively. Decrease in availability of air during the process in kJ is (S1=836J/kg.K, $2 = 787 J/kg.K) (b) 1.57 (d) 2.87 (a) 2.42 (c) 1.28 Air at state 1 at 5 bar and 1000 K having 0.01 kg mass is expanded in a reciprocating cylinder to state 2 at a pressure of 1 bar and temperature of 600 K.
