Question 3 50 Points Water Initially At 200 Kpa And 350 C Is Contained In A Piston Cylinder Device Fitted With Stops 2 (47.46 KiB) Viewed 15 times
Question 3 (50 points) Water initially at 200 kPa and 350 °C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool until the pressure is 100 kPa. a) Find the properties in each state and (10 Points) b) plot the T-v and P-v diagrams sketch, with respect to the saturation lines, the process curves passing through both the initial, intermediate, and final states of the water. (15 Points) c) The total work, in kJ. (15 Points). d) Find the overall change in internal energy between the initial and final states per unit mass of water. (10 Points) Answers: Water 200 kPa 300°C
