A 0.6-m3 rigid tank is filled with saturated liquid water at 170 °C. A valve at the bottom of
the tank is now opened, and one-half of the total mass is withdrawn from the tank in liquid
form. Heat is transferred to water from a source of 210 °C so that the temperature in the tank
remains constant. Determine (a) the amount of heat transfer and (b) the reversible work and
exergy destruction for this process. Assume the surroundings to be at 25 °C and 100 kPa.

A 0.1-m3 rigid tank contains saturated liquid-vapor mixture of water, initially at 150 kPa and 52 percent quality. Heat is now transferred to the tank until the system becomes superheated vapor and the pressure reaches 300 kPa. Determine (a) the total mass of the mixture in the tank and (b) the amount of heat transferred.

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 Saturated water vapor at 260 C is slowly withdrawn through a pressure-regulating valve at the top of the tank as energy is transferred by heat to maintain the pressure constant in the tank.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

A well-insulated rigid tank contains 6 kg of saturated liquid vapor mixture of water at 150 kPa. Initially, half of the mass is in liquid phase. An electric resistance heater placed in the tank is then turned on and kept on until all the liquid is vaporized. Determine the electrical work (Wel) in MJ

A rigid tank having a volume of 0.100 m3 contains helium gas at 170 atm. How many balloons can be inflated by opening the valve at the top of the tank? Each filled balloon is a sphere 0.300 m in diameter at an absolute pressure of 1.25 atm. (Remember that the tank cannot be completely emptied of gas.)
