- I don't think it's necessary to consider the circulation within the
- smoke bubble. Just use the appropriate dimensionless coefficient correlations
- to get the overall mass-transfer coefficient. (i.e., assume that the bubble's
- composition is not dependent on one's position within the bubble, only on the
- time spent in contact with the solvent [i.e., bongwater]).
- Hmmm.... I guess it's time to dig out the ol' mass-transfer book.....
-
- Sorry I'm just hand-waving so far. This IS the way to attack the problem,
- I'm (pretty) sure.

- The more ya goad me, the more likely you are to one day (after Midterms!)
- see the honest-to-shit equatoins on the Net...
