Heat flow between connected tanks.

Two identical tanks, each with volume 0.250m3,contain steam. Tank A contains 2.5 kg ofsteam at 400 C. Tank B contains 2.5 kg of steam at10 bar.

a. Determine the pressure in tank A. If the state is a vapor/liquid mixture, determine the mass fraction of the vapor.

b. Determine the temperature in tank B. If the state is a vapor/liquid mixture, determine the mass fraction of the vapor.

c. The two tanks are linked with a pipe and their contents are allowed to mix. The tanks are then heated or cooled, as needed, until their contents become saturated vapor. Determine the amount of heat and whether it is to be added to or removed from the tanks.

Q3. A tank with rigid walls and a volume of 0.05 m3 initially has a two-phase liquid- vapor mixture of ammonia at a pressure of 4 bar and a quality of 10%. The tank is then heated such that the pressure is kept constant through a pressure-regulating valve that allows saturated vapor to escape. The heating continues until the quality of the mixture in the tank is 40%. Assume kinetic and potential energy changes are insignificant. Determine: (i) The final...

A tank having a volume of 0.85 m^3 initially contains water as a two-phase liquid vapor mixture at 260 C and a quality of 0.7. Saturated water vapor at 260 C is slowly withdrawn through a pressure-regulating valve at the top of the tank as energy is transferred by heat to maintain the pressure constant in the tank. This continues until the tank is filled with saturated vapor at 260 C. Determine the amount of heat transfer in kJ. Neglect...
