Building an air cannon that shoots a wad of paper

  1. Sep 24, 2015 #1
    We are building an air cannon that shoots a wad of paper. I know the volume of the tank, the pressure of the tank, the size of the barrel, and the weight of the object. I need to know how to solve for initial velocity given this information. I will use the Vi to find the estimated distance.

    Weight 4.5 grams
    Max Pressure = 150 PSI
    Tank Volume = 1.25 liters
    Barrel Diameter = 1 inch

    Do I need more information?

    Thank you!
