Question:

Two insulated tanks are connected, both containing H2O. Tank-A is at 200 kPa, v= 0.4 m3/kg, V = 1 m3 and tank B contains 3.5 kg at 0.5 MPa, 400oC. The valve is then opened and the two tanks come to a uniform state. Determine
(a) The final pressure (p2),
(b) Temperature (T2) and
(c) Irreversibility of the process. Assume the surroundings to be at 100 kPa and 25oC.
