RE: [PSUBS-MAILIST] sub bouyancy

[Alec Smyth <Asmyth@changepoint.com>]

Your buoyant force will be the total displaced volume times the density of
seawater. Naturally you'll have different buoyant forces depending on
whether any tankage is flooded or blown, since that changes the displaced
volume.

I'd encourage you to consider building from plans.

Subject: [PSUBS-MAILIST] sub bouyancy


im thinking of building a sub out of a propane tank  (500 gallon), it weighs

1069 pounds ( as it sits now before ribs,con tower,tanks whatever) im trying

to figure out the bouyancy of a tank this size so i can calculate how much 
weight i can build on to it before i reach negative bouyancy,does anyone
know 
the formula for figuring this problem? hahahahaha i would hope so!!  thanks
