Air Cannon Physics

My suggestion is to take the experimental route for this. Measure values of muzzle velocity against pressure and then find the relation between the two so you have a method to predict the muzzle velocity based on the pressure. Ideally you should use something that can directly measure the muzzle velocity, if not you'll need to do calculations to take air resistance into account in the values you do measure (like how far the projectile goes).
