For a steady flow process from state 1 to 2, enthalpy changes from h1 = 350 kJ/kg to h2 = 50 kJ/kg and entropy changes from S1 = 1.1 kJ/kgK to S2 = 0.7 kJ/kgK. Surrounding environment temperature is 303 K. Neglect changes in kinetic and potential energy. The change in availability of the system is
1
320 kJ/kg
2
290 kJ/kg
3
179 kJ/kg
4
90 kJ/kg
5
120 kJ/kg
