Touching Once Again on Air Efficiency

[UpliftedApe]

KE=1/2mv^2

W=-pV

Have fun, make sure to use the right units.

Don't you need to know the mass of a paintball for that formula?

[teufelhunden]

You don't need freaking math to know that a 'Mag will get 1000 shots and a Timmy will get 1700 off a 68.45 under the same conditions.

I don't care if you do all sorts of math to tell me that the two guns are equally efficient. If you do get to that, you're missing a few things, because practically, it's not the case. Maybe it's because a 'Mag wastes more air in firing a ball than a Timmy. Maybe it's because a 'Mag can't go deep enough into a tank. Whatever it is, a Timmy gets more shots per tank than a 'Mag does.


And I'm well past middle school and Algebra I.

And Why would you start Spouting off about the practicality of another persons project? Try a new approach...like not posting anything.
A freshman in college realy isn't that far from middle school... talk louder when you get your masters.

Have fun with it UpliftedApe, let the rest of us know your results.

I was simply stating that no matter how much math anybody does, it won't change the fact that on the paintball field, a 'Mag is going to get less shots per tank than most other guns under the same conditions.

And my master's will have nothing to do with this field. MBA, more than likely.

I get about that (1000) on my level 10 emag with a 68/3000....

Prove it. That's good efficiency for any gun, let alone a 'Mag which is admittedly less efficient than most guns.

[Lurker27]

Teuf, why you bothered to post that is beyond me. It's like you're bitter for some external reason and and to take it out on mags. Mags aren't inefficient, they have fairly average efficiency. Current high end guns have above average efficiency, Some spoolers and Freestyles excepted.

And you can't really do math that will say an automag is efficient. In fact, what you'd find is that the dump chamber appears far too large (Energy content, anyway) but in fact it has to be that way to account for frictional losses, pressure drop, diabatic heating...etc.

[teufelhunden]

A 'Mag has average efficiency based on the old 15*ci shots for a 4500 tank. Stock Spyders get that. It is my opinion that the average efficiency has moved upwards; after all, the average is compiled by finding middle ground among all included in the survey.


I'm not bitter towards 'Mag. I more than likely have one coming my way within the next week or so. I posted because it is of my opinion, based on fact, that no matter what math "proves" about no one gun being more efficienct than the next, that different guns will get more shots per tank. It's true that no matter what gun is used, it takes the same amount of energy to get a paintball to go 300fps, I am not debating that. However, some guns are able to get the required energy using less air... whether the inefficiencies come from a flaw in the design or whatever reason, certain guns will get less shots off a tank. Period.

Prove it.

Not interested.

Agreed with telfu, just look at the operating pressures of a mag and another low pressure gun. A mag needs 800-1000 psi to operate, while an intimidator needs 300-500 psi. That 300-700 psi is what is going to seperate mags from low pressure guns. Not saying low pressure is better by any means though, just saying in most cases you will be able to shoot deeper into your tank.

...just look at the operating pressures of a mag and another low pressure gun. A mag needs 800-1000 psi to operate...

No it does not. Mine only needs about 500 psi.

[MindJob]

This mentality constantly amuses me.

In a country where everyone drives SUVs that get about 15mpg(myself included), and pay upwards of $2.00/gallon for gas... it amazes my everyone so concerned about the air efficency of paintball guns.

WHO CARES?

Yes, my Angel gets more shots per tank than my X-mag. Big deal. My VM-68 used to get more shots per tank than my 68-special. What the heck is that realavant to? Nothing.

Unless something has changed in the last week since I played (or since 1991 when I started playing), you could get a fill pretty cheap, and probably less than 50 ft from where you walk off the field.

...and in the case of outlaw playes (like myself also), you can rent a 80 cu FT scuba tank for $5 a day. I don't know many players who run air that dont top off between games.

The real question should be "Why is field paint still $100 a case when I can mail order the same paint for $40 shipped right to my door?"



Someone close this thread.......

[lbonettosd]

I'm with Hitech. I've got a 45/45 flatline that has a set output of 550psi for an X-valved mag and it'll shoot 280 (+/- 3FPS) across the chrono all day long. No chuffing or shootdown when you shooting long strings. Lurker27, you have asked a question THAT I (and MANY others) would love to see the answer to.

UpliftedApe, don't let ppl like teufelhunden discourage your interests.
