(b) At T = 320°C, v = 0.03 m³/kg, find p in MPa and u in kJ/kg. (c) At p = 28 MPa, T = 400°C, find v in m³/kg and h in kJ/kg. (d) At T = 10°C, v = 40 m³/kg, find p in kPa and h in kJ/kg.

2. A piston-cylinder assembly with stops (see figure) contains 1.54 kg of water initially occupying a volume of 1.25 m at a pressure of 1 bar (State 1). As the water in the assembly is heated, the pressure and temperature in the system remain constant until the piston contacts the stops. In this position (State 2), the quality, x2, is determined to be 92%. Heat continues to be added to the system at a constant volume until the system reaches a pressure of 1.5 bar (State 3). Determine the following quantities: а. X b. V2 (m2) C. W13 (kJ) d. Qu (kJ) e. Plot the results on a P-v diagram, labelling relevant P, T, and v values.
