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 rigid tank has a volume of 0.01 m3. It initially contains saturated water at a temperature of 200 oC and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line.

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 Saturated water vapor at 260 C is slowly withdrawn through a pressure-regulating valve at the top of the tank as energy is transferred by heat to maintain the pressure constant in the tank.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...
