A 0.2-m³ rigid tank initially contains saturated refrigerant- 134a at 1.0 MPa and 100
percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a at
1.6 MPa and 40°C. The valve is now opened, allowing the refrigerant to enter the tank, and it is
closed when the tank contains only saturated liquid at 1.3 MPa. The refrigerant exchanges heat with
its surroundings at 50°C and 100 kPa during this process. Determine (a) the amount of heat transfer
and (b) the exergy destruction associated with this process.
