Actually, there is no legal limit here in the Netherlands. And yes, using an airSOFT gun, which generally shoot around 70-120m/s, you can see the bb fly away, but I'm not building an airsoft gun. I'm building an air rifle, 6mm is just for the concept gun.
Homework Statement
I need to accelerate a 0.2 gram projectile to 300 m/s within 80cm. How much force (N) do I need?
Homework Equations
E = F * S
The Attempt at a Solution
How did you get those numbers? if E = F * S then 9 = 42.45 * x, then 42.45x = 9, then x = 9/42.45, x = 0.212. According to that formula the length of the barrel should be only 21.2 cm instead of 4.7 meters. ?
Another gun-related question:
I'm building a pneumatic airgun and I'm trying to find out what pressure/barrel length I have to use for a given muzzle velocity. I've done a bit of number crunching but I keep coming up with insane barrel lenghts, and that's not even considering any friction...
Hey people, first post, I'm sorry if I'm posting this in the wrong place.
How do you calculate the force exerted on a sphere? I'm building a pneumatic air rifle, and I'm trying to figure out how fast an airsoft bb accellerates with a certain pressure.
The projectile is 6mm in diameter, so...
