Hi, Ross - with a couple of exceptions, volume
calculations for geometric figures, some calculus if you want to be
nitpicky. A fundamental understanding of Boyle's Law is paramount, maybe
Dalton's Law of Partial Pressures. These are basic scuba rules in any
case.
The math involved will depend on what kind of boat
you want to build. A wet sub, a dry ambient, a one-atm. shallow
or deep, passenger load, etc. Using scuba regs, for example, in
a dry ambient sub precludes having to do life support calculations for
cabin oxygen flow, sodalime absorption rates, co2 buildup, breathing rates
at rest, heat transfer through metal hulls, etc. An extreme
example, just this side of suicidal IMHO, would be mixed gas diving in a dry
ambient. Calculating gas mixes, decom times / rates of ascent, yadda,
yadda.
A lot of the process is intuitive, however, that
being said, intuition is based on a groundwork of the fundamentals. "It
SEEMS right, therefore it should be . . ." (sorry for the dismal
paraphrase).
Hope this helps.
