Question
3.16 Two kg of a two-phase, liquid-vapor mixture of cart dioxide (CO,) exists at -40°C in a 0.05 m tank. Detern the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor C0, at -40c are ty = 0.896 x 10 m/kg and v, 3.824 x 10 m'. respectively. 3.20 A two-phase liquid-vapor mixture of a substance has a pressure of 150 bar and occupies a volume of 0.2 m'. The masses of saturated liquid and vapor present are 3.8 kg and 4.2 kg, respectively. Determine the specific volume of the mixture, in m'/kg. 3-76 A system consisting of 2 kg of ammonia undergoes a cycle composed of the following processes: Process 1-2: Constant volume from p; = 10 bar, x, = 0.6 to saturated vapor. Process 2-3: +228 kJ. Constant temperature to P- Pi. Q- Process 3-1: Constant pressure. Sketch the cyele on p-v and T-e diagrams. Neglecting kinetic and potential energy effects, determine the net work for the cyele and the heat transfer for each process, all in kJ. 3.123 Air is confined to one side of a rigid container divided by a partition, as shown in Fig. P3.123. The other side is in tially evacuated. The air is initially at Pi- 5 bar, T- s00 K and V,- 0.2 m. When the partition is removed, the i expands to fill V, - 2 V and p, = p/4. Assuming the air behaves as n ideal gas, determine (a) the final temperature, in K, and (b) the heat transfer, kJ. entire chamber. Measurements show that wable PinalRy: 3.134 One ki tylinder assembly
