PLEASE REQUEST DEMOS WELL IN ADVANCE
Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

You have selected the following Demos:
video - Laminar and Turbulent Flow
Purpose:To demonstrate laminar and turbulent flow of liquids and gases.
For laminar flow, inject one drop of food dyed glycerin into the laminar flow demonstrator (the glycerin filled cylinder) and spin the handle on top of the cylinder 5 turns in one direction, then 5 turns back. You'll see the original drop's shape magically return!
For turbulent flow, pour rheoscopic fluid into a glass tray and pull through the liquid with a wooden tongue depressor or stirring rod.
One can display this demo via a document camera. One can emphasize the rheoscopic fluid texture by using cross polarizing films.
