Black-Powder Propulsion Senior Project

[JON123]

I'm working on my senior project. The project I'm working on can be modeled similarly to a gun. I am having some problems finding a way to model pressure as a function of time as a weight/mass moves down a tube after the combustion of black-powder. Any direction in this would be great.
