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 removed, and R-12 fills up the entire volume. If the final state is 200 kPa and has a quality of 90%. Determine
(a) The volume of the tank,
(b) Heat transfer (Q) and
(c) The irreversible work. The atmospheric temperature is 30oC.
