A1. Return to your successful solution of a fairly difficult problem in one of your previous technical courses (preferably chemical engineering). Look at this solution but from the point of view of the process used to solve the problem instead of the technical details. Did you follow a structured method? Most people don’t at first. Did you eventually do most of the steps listed? Usually, the define, explore, plan, and do it steps are done sometime during the solution. Rearrange your solution so that these steps are in order. Did you check your solution? If not, do that now. Finally, try generalizing your solution.
A2. Without returning to the book, answer the following:
a. Define a unit operation. Give a few examples.
