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 and the final state is at 300 kPa with a specific volume of 0.5 m3 /kg?

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.
