Question

2. A rigid tank with a volume of 2.4 m³ contains 15 kg of saturated liquid–vapor mixture of water at 90 ° C. Now the water is slowly heated. Determine the temperature at which the liquid in the tank is completely vaporized. Also, show the process on a T-v diagram with respect to saturation lines. 3- A cooking pan, whose inner diameter is 20 cm is filled with water and covered with a 4kg lid. If the local atmospheric pressure is 101 kpa, determine the temperature at which the water will start boiling when it is heated. 4. A piston–cylinder device contains 0.8 kg of steam at 250 ° C and 0.6 MPa. Steam is cooled at constant pressure until one quarter of the mass vaporizes. (a) Show the process on a T-v diagram. (b) Find the final temperature. (c) Determine the volume change.
