In this article, the author presents five problems that are representative of some of the "movie problems" that he has used on tests in various courses, including reactor design, heat transfer, mass transfer, engineering economics, and fluid mechanics. These problems tend to be open-ended. They can be challenging and can often be worked a variety of ways--giving different answers, depending upon what basis assumptions were made. It is not necessarily expected that students get these problems 100% correct; some problems are more reasonably worked than others. What is interesting is the students' approach to the problems--their thinking process. After all, the thinking process is most of what they will retain from their college experience, not whether the Hagen-Poiseuille equation is most appropriate for laminar fluid flow rather than turbulent flow.
