Paper Details

Consider the process. The insulated tank A has a volume of 600 L, and contains steam at 1.4 MPa, 300?C. The uninsulated tank B has a volume of 300 L and contains steam at 200 kPa, 200?C. A valve connecting the two tanks is opened, and steam flows from A to B until the temperature in A reaches 250?C. The valve is closed. During the process heat is transferred from B to the surroundings at 25?C, such that the temperature in B remains at 200?C. It may be assumed that the steam remaining in A has undergone a reversible adiabatic expansion. Determine the final pressure in tank A, the final pressure and mass in tank B, and the net entropy change, system plus surroundings, for the process.
