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.

1- Suppose you are operating a steam turbine where the steam leaving the turbine is at 5 bar. This steam contains 95 wt% vapors. If the shaft work produced by the turbine is 1100 kJ/kg and the high pressure, high temperature steam enters the turbine at 100 bar (abs), what is the temperature of the steam entering the turbine? If water at 10°C is supplied to the steam boiler to generate steam, how much heat is required per kilogram of steam produced? You may assume that heat losses from the turbine are negligible.
A Boeing 767 due to fly from Montreal to Edmontonrequired refueling. Because the fuel gauge on the aircraft was not working, a mechanic used a dipstick todetermine that 7682 L of fuel were left on the plane.The plane required 22,300 kg of fuel to make the trip. Inorder to determine the volume of fuel required, thepilot asked for the conversion factor needed to converta volume of fuel to a mass of fuel. The mechanic gavethe factor as 1.77. Assuming that this factor was in metric units the pilot calculated the volume to beadded as 4916 L. This volume of fuel was added andthe 767 subsequently ran out the fuel, but landed safelyby gliding into Gimli Airport near Winnipeg. The errorarose because the factor 1.77 was in units of pounds perliter. What volume of fuel should have been added?
