Two rigid tanks are connected by a valve. Tank A contains 1 m3 of air at 1 MPa, 200oC. Tank B contains 3 m3 of air at 100 kPa, 25oC. The valve is now opened, and air flows from tank A to tank B. Before the two gases comes to mechanical equilibrium, the valve is closed. After a sufficient time, air in both tanks comes to thermal equilibrium with the surroundings at 10oC. The pressure in tank A is measured as 500 kPa. Using the PG model for air, determine.
(a) The final pressure in tank B.
(b) The heat transfer.
(c) The entropy generated in the system's universe.
