Two tanks are connected by a valve and line. The volumes are both 1 m3 with R-134a at 21oC, quality 25% in tank A and tank B is evacuated. The valve is opened and saturated vapor flows from A to B until the pressure became equal. The process occurs slowly enough that all temperatures stay at 21oC during the process. Determine.
(a) The entropy generated.
(b) The total heat transfer.
