Fluids

I finished a big scientific computing problem set last night (all except for one question) and sent it in about 11:00. It was due at midnight. I'm feeling slightly better about that class, but I'm sure the doom will return soon enough. Like maybe while studying for the midterm, week after next.

Right now I'm working on a take-home exam in fluid mechanics. We had a week to do it, but I didn't get started until today, due to the scicomp work. Right now I'm looking at a blank page and a big fat zero!

Problem 1 has to do with the rate of expansion of an exploding fireball. You get 30 points for deriving the equation that describes it, and 100 extra credit points for solving it (a hint, I'm assuming, that it can't be done).

Problem 2 has to do with rain running down a sloped roof and we're supposed to derive equations for the thickness of the layer, the pressure inside it and some other things.

Problem 3 has to do with a pulsating bubble of gas inside a liquid. We get 10 extra credit points if we include the effect of surface tension.
