**C1.** Determine the effect of pressure on the temperature, separation and diameter of a flash drum.

**C2.** Solve the Rachford-Rice equation for V/F for a binary system.

**C3.** Assume that vapor pressure can be calculated from the Antoine equation and that Raoult’s law can be used to calculate K values. For a binary flash system, solve for the drum pressure if drum temperature and V/F are given.

**C4.** Derive Eq. (2-24) and show that it is correct.

**C5.** Choosing to use V/F to develop the Rachford-Rice equation is conventional but arbitrary. We could also use L/F, the fraction remaining liquid, as the trial variable. Develop the Rachford-Rice equation as f(L/F).

**C6.** In flash distillation a liquid mixture is partially vaporized. We could also ...
