I'm designing a tennis ball launcher using compressed air that will hopefully be able to hit a target at some distance away. We won't know the exact distance until the day of the competition, but I was curious if there was some relatively simple equation relating the pressure of the compressed air and the initial volume of it to the exit/muzzle velocity of the tennis ball as it exits the barrel.
Given the range, and I was thinking of just using a static launch angle of 45 deg., it would be fairly simple to calculate the required exit velocity but then relating that to what pressure I would need to fill the chamber up to is eluding me. Any help would be greatly appreciated. Thank you.
