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 rigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 1 MPa and 300°C. Now the valve is opened,and steam is allowed to flow slowly into the tank until the pressure reaches 1 MPa, at which point the valve is closed. Find the rate of entropy production.

A well-insulated rigid tank contains 5-kg of a saturated liquid-vapor mixture of water at 100 kPa. Initially, three-quarters of the mass is in the liquid phase. An electric heater with a power rating of 880 W is placed in the tank. Determine how long it will take to vaporize all the liquid in the tank. Show the process on a T-v diagram with respect to saturation lines.

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.

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...

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 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saturated liquid water at 170 °C. A valve at the bottom of the tank is now opened, and one-half of the total mass is withdrawn from the tank in liquid form.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...
