Calculating the hydrostatic pressure on a tube

AI Thread Summary
The discussion revolves around calculating hydrostatic pressure for a submarine project involving a perspex tube designed to be submerged to 100 meters. Key parameters include the tube's dimensions, material properties, and internal pressure. Participants suggest utilizing online engineering calculators and provide relevant resources for strength calculations related to pressure vessels. The original poster expresses gratitude for the helpful links, particularly one that meets their needs. The conversation emphasizes the importance of understanding deformation, critical pressure, and potential failure modes in design.

Hey guys.
I'm working on a submarine project and my goal is submerging it to 100m, but I'm having trouble calculating the parameters i need.
I'm working with a perspex tube (E is about 1.3Gpa), 26mm inside diameter and 30mm outside diameter. the tube X meters long with inside pressure of 1 atm.

I'd be happy if you guys could direct me to the right formulas (and how to derive them) for the deformation (ε), the critical pressure (Pc) and would it fail from buckling or by compression.

Thanks for the help! very much :)

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
