30 something BPS = Paint collide in air?

I own Utdragun

Ok, well I was obviously wrong, which is why im still learning, I take physics next year so I was going off wrong information told by word of mouth.

[UTDragun]

There is a limited ROF, but you've got the wrong source. The limit on the ROF for all projectile launchers (firearms, paintball markers, or catapults) is how long it takes to load the next round.

well I was not counting load speed, thats obviously the first limiting factor, considering its very hard to feed over 30 bps as it is. but if you took that out as well as the force on the pb coming into the breech from the stack and the forward pressure from the bolt, it would be limited on how fast the air could accelerate the ball.

I don't think it's very likely at all that a couple paintballs managed to bounce off the can or whatever they were firing at, head straight back at the shooter, hit another paintball in midair and bounce off. C'mon guys. Bounces aren't too likely to begin with, and they usually happen on soft surfaces and/or at an angle. How many times have you seen a ball at 300FPS hit a hard surface and bounce straight back? And then you expect us to believe that two balls hitting head-on (combined speed of 600FPS here) aren't going to break, but instead bounce off?

It's most likely that the colliding paint was going the same direction and only hit due to velocity inconsitancy. There's just no other possible way for it to happen.

This could be Deep Blue material, though. I'd like to see some of the more scientifically-inclined among us weigh in on the issue.

I've had paintballs hit hard surfaces and bounce back towards me. It happens more often with cheap paint.

you mean this vid?

http://media.putfile.com/UFS8-First-Look

I only watched it once, wasnt really paying much attn but i didnt see paint coliding

yes, that vid, at 2:36 in the vid, it has a slow-mo down the barrel shot, and you can see 2 balls collide, neither break, but they shoot off in opposite directions after impact.

It's true....happens to me all the time.

I shoot so fast that the balls in front create a time and space vortex that envelope the following balls and transport them to a point in time in the very near future (small vortex apparently) ...which sometimes , unfortunately puts it in the exact physical location as the ball that created the vortex in the first place. Since we know thru science and James T. Kirk , no two bodies can occupy the same space (except for Kirk and a sexy green alien intruder) one of the 2 balls comits suicide in order to save it's bretheren.

Pretty simple really.

which is why, after thorough research and testing, the major leagues are capped at 15, and most guns will never shoot above 30 bps (except for our magic mags of course ). in fact, if you manage to get up to a sustained 35bps, you may very well end up shooting yourself in the back of the head.

for the collision in the vid that i commented on:

i do know that the ball wouldnt have to have a direct hit, (in the case of them coming from opposite directions, they would bounce backwards, or actually break on each other) (in the highly improbable, nearly impossible case that they were coming from the same direction however, they would need to somehow have one fall onto the other, while the other is lifted up to cause that kind of a deflection.)

as for the people who doubt the ability to bounce from a garbage can: ive done it many times, off garbage cans, hyperball tubes, oil drums, etc.

also, in the video, they specifically state that the pain they are using was from 2004. ive found that in general, older paint seems to be more bouncy when it hits the target. however, it is possible that they did switch paint, etc. it is probably safe to assume that it was the paint they were talking about.

[SCpoloRicker]

Someone was saying, a long time ago, that they had a video, where they reached the maximum BPS for a paintball marker

I think it was 30 something, and you could see the balls colliding in mid air...


Anyone know what i'm talking about? Or have a link to a vid?

it happened to me when i first got my borg actually. it wasnt too consistant cause it wasnt taken care of, and when the air pressure started dropping the balls would shoot at drastically different speeds. a few collided in midair, and i thought i was chopping at first but when i took off the barrel it was clean.

have you been talking to doc recently?

Now that's what I'm talkin' about.

[VFX_Fenix]

Woo hoo, spread sheets!

Anyway, so here's some raw number crunching, and I admit that I'm very suprised... well... not really... but the long and short, unless you have some serious... and I mean SERIOUS velocity issues, this should never ever happen over normal paintball distances. Also bear in mind that deceleration caused by drag is not anywhere in this equation. Anyway...

Orange indicates more or less typical close, Yellow medium/long, and the Grey line at the bottom is more or less maximum range of a paintball. Numbered ball columns are all assumed to be the ball preceding ball X. Blue boxes are when Ball X would arrive at a numbered ball when Ball X is fired imediately after the numbered ball. All time intervals are set to 36bps (0.0277sec) and the numbers in the columns represent feet traveled by their respective balls.

[behemoth]

Holy hell, i was just asking for a vid, someone said they had around a while ago..

I didnt expect a philosophy debate

[warpspyder]

Zakvetter did 34 if im not mistaken.

In a perfect world, (no air resistance) 300Fps/30 bps = 10 feet apart.

And does paint follow a predictable path? Hardly. It would take an extreme set of circumstances for paint to collide. Dumb luck, and a horribly inconsistent gun.

[athomas]

I like the chart.

It shows that there is a possibility of a trailing ball catching a ball fired before it. However, even major velocity fluctuations of 25fps made that impact occur over 90 feet out. A velocity idfference of only 25 fps wouldn't cause the ball to break upon impact.
