how much external pressure can tanks withstand before rupture?
(please read rest of details! )
I KNOW it will be far deeper than a person could actually dive with scuba tanks. I am not looking for the maximum depth a person could reach.
Go to the deepest part of the ocean, put weights on the tanks so they will sink instead of floating, and let them go. How deep do they reach before the water pressure crushes the tanks and releases the air?
Also, will the answer vary depending on whether the tanks are full or empty? Does the internal pressure of the tank help to resist the external pressure of the water?
Finally, can analogous values be found for propane tanks, CO2 tanks, etc?
Which ones would provide the greatest buoyancy?
I may not be expressing this properly. Please be patient with me. If you don't understand, ask for more details and I WILL provide them. Thanks to all who give serious replies!
