20:06 O WHATSAPP now Ali Janbein @ cuuui والمعنی 3.16 Two kg of a two-phase, liquid-vapor mixture of carbon dioxide (CO,) exists at -40°C in a 0.05 m' tank. Determin the quality of the mixture, if the values of specific volu for saturated liquid and saturated vapor CO, at -40c are ty = 0.896 x 10 m/kg and v, = 3.824 x 10 m'a. respectively. 3.20 A two-phase liquid-vapor mixture of a substance has 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. Constant temperature Process 2-3: +228 kJ Ps= Pi. Q- to Process 3-1: Constant pressure. Sketch the cycle on p-v and T-U diagrams. Neglecting kinetie and potential energy effects, determine the net work for the cycle and the heat transfer for each process, all in kl. 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 evaeuated. The air is initially at P 5 bar, T- s00 K and V,- 0.2 m. When the partition is removed, the air expands to fill the entire chamber. Measurements show the V - 2 V, and Pa= P/4. Assuming the air behaves as ideal gas, determine (a) the final temperature, in K, and (b) the heat transfer, kJ. Finally:
