Hi Ward,

>Please correct me if I'm wrong, but isn't 33 feet 1 atmosphere?  The
pressure at 8 feet is almost trivial. 

0'  = 1 ATM
1 ATM = 14.7 psi
33' = 2 ATM (2 ATM is actually 32.8')
8'  = 2.5m
    = 1.25 ATM
    = 18.4 psi (true, pretty trivial)

i've rounded a little in the sums :)

14.7 psi seems higher than my faded pre-metric memories suggest.  can anyone confirm this is correct?

the conversions were done by:
