Introduce the Reynolds Number as the "judge" that decides if a flow is orderly or chaotic.
Before the video reveals the outcome, pause it. Ask yourself: Based on Bernoulli’s principle, what should happen to the pressure here? Write down your prediction, then play. If you are wrong, rewind and analyze why. fluid mechanics videos
These are computer-generated simulations that reveal internal pressure and velocity contours that physical experiments cannot. Introduce the Reynolds Number as the "judge" that
