Initially (state 1) a well-insulated rigid tank contains 20 kg of a saturated liquid-vapor mixture of water at 100 kPa and half of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized (state 2). Determine (a) the initial specific volume in m3/kg, (b) the final specific entropy in kJ/kg.K and (c) change of entropy in kJ/K.

An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...

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 Saturated water vapor at 260 C is slowly withdrawn through a pressure-regulating valve at the top of the tank as energy is transferred by heat to maintain the pressure constant in the tank.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

A closed, rigid tank is filled with water. Initially, the tank holds 1.0 lb of saturated vapor and 7.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

A rigid, well-insulated tank contains 100 kg of liquid water at 21°C. The tank is connected through a valve to a steam main where the pressure is 1 MPa. The valve is opened and steam enters the tank until the water temperatuere rises to 65 °C, at which time the valve is closed. It is determined that there are now 107.96 kg of water in the tank. Estimate the quality of steam in the main.
