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 special mud formed by mixing dry clay and water is used to assist drilling through rock. The optimum amount of clay in the mud is determined from a chart that relates the percentage of clay to the hardness of the rock. If a supply of mud containing 38 percent clay and the rest is water that is available, how much of this mud and how much dry clay need to be mixed to produce one ton of a mix containing 48 percent clay?
