Homework Statement If a one cubic foot balloon is reduced to half the volume at 2atm or 33ft of water and is two times as dense, Is water at that depth also two times as dense making bouyancy constant at 2atm or even deeper? Homework Equations The Attempt at a Solution

If a one cubic foot balloon is reduced to half the volume at 2atm or 33ft of water and is two times as dense, Is water at that depth also two times as dense making bouyancy constant at 2atm or even deeper?

Even when talking about 3-6atm´s? Understandable that everything has it´s limits. I´m looking at for example: a steal structure and trying to find a formula to estimate the wall thickness, considering there would be let´s say 6 atm´s of pressure or let´s say five to make the math easier. Thanks...

I´m trying to find approx. numbers or formulas for a submarine like structure to mantain a constant volume. For a given volume, which materials and to what thickness should the container be?
