CBE 30355 - Lecture Notes - Sept. 14, 2010

Announcements

Class notes

The main points of the lecture were

• Conservation of Momentum

Goals:

• Derive an integral equation governing conservation of momentum.
• Apply it to determine all relevant forces in a pipe or other geometries.

Reading

• The class notes.
• BS&L, chapter 2

Additional Readings:

In our class demonstration today we looked at how a thin drop of dye (water) breaks up when dropped onto a concentrated surfactant (Triton X-100). The water drop was torn apart forming streamers and several generations of a fractal pattern. Fractals are the result of non-linear dynamical systems, and are studied in the general field of Chaos Theory. For an introduction to this area, as well as some really neat pictures, go here.
