Question 1 Marks 20 (a) Water is contained in a closed, rigid, 0.2 m3 tank at an initial pressure of 5 bar and a quality of 50%. Heat transfer occurs until the tank contains only saturated vapor. Determine: (i) (ii) the final mass of vapor in the tank, in kg, the final pressure, in bar. [4 marks] [4 marks] (b) 2000 kg of water, initially a saturated liquid at 150°C, is heated in a closed, rigid tank to a final state where the pressure is 2.5 MPa. Determine: (i) the final temperature, in °C, [4 marks] (ii) the volume of the tank, in m3, [4 marks] (iii) sketch the process on T-v and P-v diagrams. [4 marks]
