A piston-cylinder assembly contains a two-phase liquid-vapor mixture of water with an initial dryness fraction of 50%. The mass of the piston is 15 kg with a diameter of 10 cm. The surroundings exert a pressure of 1 atm in the piston. Heat is added to the system under the isopiestic process until the piston hits the stops. The final condition of the steam is saturated vapor. Determine the work in kW if the mass of the mixture is 17.521 kg/s.

Chemical and Phase Equilibrium

Phase diagrams or equilibrium phase diagrams are the graphical representations that show the phase transformations of the constituting elements with respect to the pressure, temperature, and compositions. The diagrams show the conditions that limit the different phases, namely solid, liquid, and gas. The diagram can also be utilized to verify the relations between the state variables. Most of the phase diagrams are temperature-pressure phase diagrams, with the variable parameter as the composition. Usually other variables such as solubility and pressure parameters are not indicated in the phase diagram. For a one-component system (unary phase diagram), the phase diagram is generally a function of temperature and pressure as the state variables, or temperature and volume. However, for a binary system (two-phase) having two components, the phase diagram is a function of temperature and composition as the state variables only. Coexisting of the different phases of the constituting elements is indicated in the phase diagram. A ternary phase diagram can be characterized by consisting of three phases in equilibrium.
