Illustrated Experiments in Fluid Mechanics - Ascher Shapiro - MIT

These videos are a real drag, but do not let that keep you from watching them.





These videos were produced by the same National Committee for Fluid Mechanics Films that made the films I wrote about a few weeks ago. Unfortunately, these videos do not have the PDF transcript files that those other videos have. But fluid dynamics drag is such an immensely important subject, I had to write about it.

By the way, something does not appear to be quite right with the videos. The third video seems to really be the end of the second one. Most of the third video is a blank screen. The information that they do contain is great, but I wonder if a video or two is missing.

Fluid Quantity and Flow

There are four videos in the drag series. The last four videos below belong to an entirely different series entitled Measurement. It is really about different ways of measuring fluids, both standing and flowing. There are no transcripts for these videos, either, but they look newer than the drag series. In fact, they look to me like converted VHS tapes.

That is the good news. The bad news is that they have terrible background noise. It is a real shame that a better attempt was not made at cleaning up the sound. But if you can look past this deficiency, you will be rewarded by another well-made educational video series.

There is a lot of discussion in these videos about measuring liquid fluids such as water and gasoline. The stuff that you are looking for is towards the end. There is an excellent discussion there of measuring air pressure using a pitot tube, for example. Ways of visualizing an air flow over a wing, for example, are also covered.

As expected, these videos are all jam-packed full of information. Everything is not just discussed, but also demonstrated. They are really quite good.

School-Wide Modular Program for Fluid Mechanics

An interesting related link is the School-Wide Modular Program for Fluid Mechanics. Also sponsored by the Massachusetts Institute of Technology (MIT), it is an attempt to locate in one place information for teaching fluid mechanics principles.

In particular, one of the modules already online is about low Reynolds number flows. This is still very much a work in progress, and the information contained in the modules is very incomplete.
