[Note: this is an open-ended problem. Various answers are possible, but some answers are better than others. The intent of such problems is to force us to use our knowledge of fluids while keeping in mind practical constraints such as time, money, and measurement capabilities.] (5 points) The objective of this problem is to devise an inexpensive but effective manner for measuring liquid viscosity at room temperature. We can use the concept of terminal velocity to help us measure viscosity...
