A tank whose volume is unknown is divided into two parts by a partition. One side contains 0.02 m3 of saturated liquid R-12 at 0.7 MPa, while the other side is evacuated. The partition is now removed and R-12 fills up the entire volume. If the final state is 200 kPa, quality 90%, determine.
(a) The volume of the tank.
(b) The heat transfer.
(c) The entropy generated. The atmospheric temperature is 30oC.
