Re: Re: [PSUBS-MAILIST] Pressure calcul

[Roger June <rjune@fuse.net>]

I think your right ...didn't think about the fact that the sub hull would not see the force from the initial 1atm because it is balanced out by the 1atm of pressure on the inside of the hull. (most of the time when I deal with theses types of presures I'm using them to figure partial pressures for gasses in which case the 1atm does apply.)
