Two rigid tanks are connected by a valve as shown in the accompanying figure. Tank A is insulated and contains 0.1 m3 of steam at 500 kPa and 90% quality. Tank B is uninsulated and contains 2 kg of steam at 100 kPa and 300oC. The valve is now opened, and steam flows from tank A to tank B. As the pressure in tank A drops to 300 kPa, the valve is closed. During the process 500 kJ of heat is transferred from tank B to the surroundings at 25oC. Assuming the steam in tank A to have undergone a reversible adiabatic process (isentropic), determine.
(a) The final temperature in each tank.
(b) Final pressure in tank B.
(c) The entropy generated in the system's universe.
