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. Fish is used in animal feed by removing the fish oil and then drying the remainder into a cake that is mixed with other feed. One operation feeds 2 640 kg/h of fish that contains 5.27 percent oil, 73.8 percent water, and the balance is dry fish cake. The fish cake produced has 0.123 percent oil and 12.7 percent water. How much water is evaporated during the process if the fish oil contains 1.25 percent water?
