Question Ref. No: 2916 Two tanks (Tank 1 and Tank 2) are separated by a partition. Initially Tank 1 contains 2.2 kg steam at 1 Mpa and 400 oC while Tank 2 contains 3.6 kg saturated liquid vapor mixture at 165 oC with a vapor mass fraction of 70 percent. The partition is now removed and the two sides are allowed to mix until the mechanical and thermal equilibrium are established. If the pressure at the final state is 400 kPa, determine (0) the temperature and quality of the steam (if mixture) at the final state and (i) the amount of heat lost from the tanks. Ans: (i) Temperature 143.61 oC,x=0.51. Heat lost= 1JJ. Format answer: 5758.27
