Problem #3 (10 points total) A tank having a volume of 0.85 m³ initially contains water as a two-phase liquidvapor mixture at 260C and a quality of 0.7. Saturated water vapor at 260C is slowly withdrawn through a pressure-regulating valve at the top of the tank as energy is transferred by heat to maintain constant pressure in the tank. This continues until the tank is filled with saturated vapor at 260C. Determine the amount of heat transfer, in kJ. Neglect all kinetic and potential energy effects. Pressure regulating valve Saturated water vaper removed while the tank is heated Initial: two-phase liquid-vapor mixture Final: saturated vapor
