**G1.** Solve for Q_{c} and Q_{R} in Problem 3.D1 with a process simulator.

**a.** Part a.

**b.** Part b.

Note: With Aspen Plus, use RADFRAC (see Appendix to Chapter 6, Lab 3) with an arbitrary (but large) number of stages and feed location = N/2. Do calculation for D by hand and input correct values for D and L/D (or *V/B*).

**G2.** [This problem should be done after studying the Appendix A of Chapter 4.] Solve Problem 3.D6 using AspenPlus to find Q_{c} and Q_{R}. To do this, do a hand calculation to find the value of D. Then arbitrarily set N = 40 and N_{feed} = 20 in RADFRAC and do the simulation.
