C. Derivations

C1. Derive Eq. (7-17). Derive an equation for (FRC)bot in terms of (FRA)dist.

C2. Derive Eq. (7-34).

C3. If the pinch point occurs at the feed point, mass balances can be used to find the minimum flows. Derive these equations.

C4. The choice of developing the Underwood equations in terms of Vmin instead of solving for Lmin is arbitrary. Rederive the Underwood equations solving for Lmin and Imagemin. Develop the equations analogous to Eqs. (7-29) and (7-33).

C5. For binary systems, Eq. (7-33) simplifies to a linear equation for both saturated liquid and saturated vapor feeds. Prove this.
