Velocity of a cap on a pressurized chamber 1

[BlaineW]

My inability to google the missing pieces has left me seeking help from the community.

I'm working on a concept project and unfortunately I can't get into too many details.

Imagine a scenario of a pressurized chamber that has a cap of some sort. Imagine it is suddenly released and allowed to shoot off under high pressure. Is there a non experimental way to determine what sort of velocity the cap would fly off at?

The initial force applied is easy enough to figure out, but it would drop very quickly as the pressure dies off, so how does one evaluate the dynamics?

What are some assumptions that should be made?
What equation(s) can be used to predict either the force on the cap as it relates to time/pressure drop, how does the pressure drop nover time?

I would appreciate any insight,

Thanks.

Ah, yes, Snorgy, and a star for the reminder, LOL. Isn't that a corollary of Murphy's law?

Ok, it's Christmas. BlaineW, you've been led down a lot of garden paths, but hopefully you've learned something. If you don't want a pipe plug to fly around and do damage, do something positive to restrain it (put a strap on it, or a cage around it...), or design it out of your system. If you DO want a pipe plug to achieve high velocity, then design a gun barrel.

It's be nice for Blaine W to come back and let us know if anything that's been said has been of help to him.
