In a zoo in California, a mother tiger gave birth to a rare set of triplet tiger cubs. Unfortunately, due to complications in the pregnancy, the cubs were born prematurely and due to their tiny size, they died shortly after birth. <br /> <br />The mother tiger after recovering from the delivery, suddenly started to decline in health, although physically she was fine. The veterinarians felt that the loss of her litter had caused the tigress to fall into a depression. The doctors decided that if the tigress could surrogate another mother's cubs, perhaps she would improve. <br /> <br />After checking with many other zoos across the country, the depressing news was that there were no tiger cubs of the right age to introduce to the mourning mother. The veterinarians decided to try something that had never been tried in a zoo environment. Sometimes a mother of one species will take on the care of a different species. The only "orphans" that could be found quickly, were a litter of weaner pigs. The zoo keepers and vets wrapped the piglets in tiger skin and placed the babies around the mother tiger. <br />

Anyone compare compressed gasses in avy bag performance in the States & Euro? We typically see air here, whereas more nitro use over there; correct or no?

I saw this discussion, but it was more about decision making & gadgetry:

Nitrogen works better in colder temperatures than compressed air is the main difference. Compressed air still has some moisture and other trace gasses which makes it react more drastically to temperature changes. The moisture could also drop out and freeze, but that would have to be a pretty extreme drop in temp.

Air is greater than 70% nitrogen, so the point is moot.

You could probably use the equation PV=nRT to calculate a few test samples if you are really interested. However you will probably need to figure out the partial pressure based on the ratio of gasses combined in the sample.

I'm actually finding that it is not all that moot.

Theres a huge difference in Nitrogen, CO2 and Air when it comes to cold temp performance in paintball. Nitrogen is the most consistent due to its extremely low moisture content

If you would like to further investigate and help me design a model I could run the calculation in Gaussian next time I get some free time at school.

Sorry to burst your bubble but no one fills HPA tanks with nitrogen anymore. And Co2 is actually changing states when it escapes your tank so that's a different problem all together.

I would HIGHLY doubt that an airbag system would deploy any fast or more efficiently with compressed pure Nitrogen vs compressed atmosphere.

No bubble to burst here. But HPA is for air....and there are plenty of players and entire teams that use Nitro all the time for paintball, with good reason. Yes CO2 is put in as a liquid...which wouldnt be practical for the avy bag use. I was simply stating that N is way more efficient and reliable at colder temps. (Mark stated "air is 70% N so that point is moot") so I have to agree with Buff in that its not moot. If you fill a tank with N and another tank with Air, at room temperature, and then take it into a cold environment the N will be more reliable and efficient than the air.

I'd like to see what teams/ parks/ events are still using Nitrogen. Cause I sure as hell know that PSP, NPPL, and large fields are just using compressed air. Also having the gas regulated 1-3 times before it gets to fire or actuate anything takes the difference between the two and makes it moot in relation to regulator efficiency. BTW I'm not talking out my ass on this, been in PB for over a decade and gun tech'd for a good portion of that.

Just interested what your experience with MO Theory is?
