Ok, in the midst of another discussion I started wondering
about bouyancy and well, let me illustrate with a
word problem :-)

1a)You are neutrally bouyant at X fsw.  You instantaneously (I'm
guessing this assumption helps out the mathematics, ignore
it if it doesn't) inflate your BC such that you are Y lbs
bouyant at that instant**.  Now assuming a BC with infinite volume
(as the air expands as you ascend) how long does it take you
to get to the surface, what is your speed (assume a point mass?),
and how far do you shoot out of the water? :-)
1b)Now assume a self-venting BC with a limited bouyancy of
say Z lbs, again what are your exit data?

anyway, I'm partly interested in these kinds of answers,
moreso in the principles needed to answer them.  I have no
idea exactly how hard this is, nor how many assumptions
(about surface area, resistance, etc etc) one has to make 
for a reasonable first or second order approximation.

Jack and Jill level (or slightly better) explanations welcomed, 
or even better a pointer to a decent reference.  

Thanks,
Mike

A is A.    Man who say it cannot be done should not interrupt man doing it.
