Make your own potato gun and impress your Never point the potato gun in a direction that you do not wish to shoot. Re For a fixed barrel length, this equation suggests that the muzzle velocity can be enhanced by maximizing the product of the initial pressure and the volume of the propellant gas and decreasing Spud launcher construction and safety at Burnt Latke. Maximum pressure will be 820 kPa (120 PSI) – Check Would a potato gun with a smaller diameter barrel shoot faster or slower than one with a larger diameter? I'm trying to run the numbers on this, and it's not making sense to me. The potato sits at the base of this barrel, forming a seal. This modified barrel loads just like a regular breech loadin rifle. Keeping the size of your projectile " slightly " The potato would exit the barrel before the combustion had reached maximum force, the chamber might explode as well. Because the Potato Cannon 5000 is On this page, I will attempt to calculate the affect on the muzzle velocity of changing the chamber volume on a fixed geometry barrel.
