Goals:
After this class you should be able to:
- Calculate pressure distributions in fluids at rest.
Reading
- The class notes.
- BS&L chapter 1, WWWR chapter 2
Additional Readings:
One of the fluid properties we talked about last Thursday was the coefficient of
thermal expansion. To see an extreme example of what can happen if this property
is ignored, check out the link given
here.
Demonstration:
In class today we demonstrated how to tell a raw egg from a cooked one by
spinning it. In addition to this effect, cooked eggs also have the interesting property
that they tend to "pop up" on their ends when spinning. The mechanics of this phenomenon
are actually quite complex, and only recently was solved by Keith Moffatt of the
University of Cambridge.
