Re: [PSUBS-MAILIST] Equasion Query

["Pierre Poulin" <pipo305@hotmail.com>]

Jasper,

We can say that water is not compressible. Your sub shouldn't too. So the 
displacement is the same at whatever deep.

What you are talking about is an ambient pressure sub: pressure outside = 
pressure inside. Whatever the design, exept wet sub (fill of water)the 
displacement/bouyency remain the same.

Pierre

P.S. Don't hesitate to pose questions, it's the purpose of this group!
P.P.S. please, present yourself to the group!
