Supplemental Video for Lab 2: Flow Visualization in a Pipe (8 min.)
This video discusses the Reynolds Apparatus. The video shows flow the transition from laminar to turbulent flow in a round pipe using the Reynolds apparatus.  Flow is laminar for approximately Re<2300.

Lab 3: The Impact of Jets (9 min.)
This lab involves the measurement of the impact force of a water jet on a target. The measurements are compared to predictions from theory momentum conservation principles on a control volume (covered in Chapter 3).
