Follow the steps of the Systematic Approach of Section 14.4—that is, (1) identify the system, (2) determine whether the process is batch or rate, (3) construct a schematic diagram with inputs and outputs, (4) Label known material quantities or rates of flow and so on. A process requires two distillation columns. The first column is fed a solution containing 23 percent component A, 29 percent component B, the rest component C. The product amount is one-third of the feed amount and contains 61 percent A, 5 percent B, the rest C. The bottoms amount is fed to a second column which then produces a product of 15 percent A, 79 percent B, the rest C. The waste from the second column contains 0.50 percent A, the rest B and C. If 3 300 lb of solution is fed to the first column, determine the
