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. Two liquids, A and B, are mixed together. A is 3.0 percent solids, the remainder water. B is 8.0 percent solids, the remainder water. An amount S of pure, dry solids is mixed with A and B to form 2.0(102) kg of a mixture with 5.0 percent solids. Develop a table of combinations of amounts of A, B, and S that will satisfy the final mixture requirements. What is the maximum amount of B that can be used to meet the requirements without having to remove pure, dry solids from the mixture? Hint: Write a short computer program

Question

or use a spreadsheet and start with B = 0 and increase in increments of 2 kg.

What will be an ideal response?
