17- Two rigid tanks are connected by a valve. Tank A is insulated and contains 0.2 m of steam at 400 kPa and 80 percent quality. Tank B is uninsulated and contains 3 kg of steam at 200 kPa and 250°C. The valve is now opened, and steam flows from tank A to tank B until the pressure in tank A drops to 300 kPa. During this process 600 kJ of heat is transferred from tank B to the surroundings at 0°C. Assuming the steam remaining inside tank A to have undergone a reversible adiabatic process, determine (a) the final temperature in each tank and (b) the entropy generated during this process. Answers: (a) 133.5°C, 113.2°C; (b) 0.916 kJ/K

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. An adiabatic air compressor compresses 10.4 L/s of air at 120 kPa and 20°C to 1000 kPa and 300°C. The constant pressure specific heat of air at the average temperature of 160°C = 433 K is cp= 1.018 kJ/kg.K. The gas constant of air is R = 0.287 kPa.m³/kg-K. 1 MPa 300°C Compressor 120 kPa 20°C Vus Determine the work required by the compressor. (You must provide an answer before moving on to the next part.) The work required by the compressor is -4.578 kJ/kg.
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.
