I Conditions of collapsing a container

  1. Jul 25, 2016 #1
    Hello, I have some sort of problem which I would like to explore. We have yet to touch it in the class in the university, but it seemed like a crazy idea when i stumbled upon it.

    Let there be a very long pipe with an inner radius of 1.08 meters and outer radius of 1.1 meters. The material of the pipe is steel. Inside the pipe there is 1 millibar of pressure while on the outside 1 bar of pressure. Would the container withstand the pressure difference? If not, what would it take to reinforce the steel to as such that it would withstand this pressure difference?

    If calculations and equations can be provided, that'd be great.

    Essentially something like that, yes.
