Alright, So for my Grade 11 class our project was to design and build something that shows scientific characteristics. I decided to make a golfball cannon
It uses a regulator with a schraeder valve to fill with air. In one shot we used 80 Psi to shoot a golfball with a diameter of 1.68 inches. Our chamber uses 2'' ABS pipe, which I calculated to have a volume of approximatly 0.618 L per sq foot. Our pressure chamber is 5' long in total, where it leads to a quick release valve. We use very tight wadding for our golfball so it fits the barrel, which has an inside diameter of 1.7'', very nicely. We shot on a 45 degree angle, and our golfball has a mass of 1.620 ounces (45.93 g)
Is there any way someone could help me with this, perhaps there is an equation that would be used to find projectile distance or atleast something that I could show, like velocity or acceleration when shot. Any other variables copuld be estimated, or ask me and I may be able to tell you.
