5 kg of water at 2 ° C, 2 kg of ice at 0 ° C and 5.5 kg of water vapor at 120 ° C and 1.5 bar are mixed in a fixed-volume container. What is the final temperature of the mixture? How much water vapor condenses? Suppose that the volume of the container is constant with a value equal to the initial volume of the water vapor and that the container is insulated. Suppose it is a discontinuous process (batch or lots).

A mass of 5.5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 101.325 kPa. Initially, 2.3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 21 percent. Determine: a) the initial...
