Nitrogen... in tires?

I think that I'll use Helium in my tires -
- it makes the car lighter!

That's right!! Less unsprung weight!!! (but does it make the exhaust sound funny?) /bcforum/images/%%GRAEMLIN_URL%%/jester.gif
 
Well you have to be careful of them Ingineers,they put Oxigen inside space capsules too. /bcforum/images/%%GRAEMLIN_URL%%/rolleyes.gif---Keoke--AZ--- /bcforum/images/%%GRAEMLIN_URL%%/cowboy.gif

keoke, yah, that was a bad one! /bcforum/images/%%GRAEMLIN_URL%%/frown.gif
 
The tire is a bit low. I'll check with her to see if costco will rotate for free and top it off with some a that there nitrogen.

His statement was, The reason bieng it can escape from a smaller imperfection {Hole} than regular air can!
But then thats the Govt. and thier ideas of "How we do things"
There is the right way, the wrong way, your way, my way,
and the Govt. way of doing things.
So Nitrogen @ 300 P.S.I. for 5 minutes, no escaping bubbles from anywhere it was!

Never the less i`m still not using it in my tries anytime soon.

Your engineer apparently didn't know the difference between Helium and Nitrogen. Helium is regularly used for leak testing in sealed devices (the standard technology for about 50 years+) it is good since it does actually go through small imperfections at a high rate (low mass, small physical size and very high speed) A Nitrogen molecule consists of two atoms, Helium only one very small atom. Helium is also good for leak detection since it exists in very low quantities in normal air so it is easy to detect when it does exist.
I worked on a project a few years ago where we had to leak test an important pressure sensor at actual working pressure: 5,000 psi! Any gas is real scary to work with at high pressure like that.
 
70herold, im sure the dangers of working with that high pressure helium was some what relieved by having everyone around sounding like "munchkins". /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif

One thing I neglected to mention is, some of the parts on the T-700 {G.E. Gas Turbine engine actualy belong to General Electric. {The Government DOES NOT actually OWN these parts!} That bieng said, I`m positive that any work done on these parts {Compressor and 1st, 2nd & 3rd stage nozzles included}, permission and the S.O.P. has to be given by G.E. and specificaly followed. Therefore it is highly likely that this "Nitrogen" test came specifically from G.E. Never the less I.M.H.O. I could not then, and still can not for the life of me see the reasoning behind using Nitrogen for this test.
But when you are a Peon W.G. yours is not to question but to do as you are told.
{I know first hand lol, too many times I`v been in HOT WATER for asking what the G.S.`s and W.D`s deemed insignificant questions.}
Here is one even better ....... thier answer to many of my Insignificant questions ....... "Because thats the way we`ve always done it". Yep ..... laughable at best.
My reply to them ....... "it`s your nickle" {But then i`v been paid $25.00 per hr. to police ciggie butts too! Some sort of punishment for bieng too inqusitive I suppose}.
B.T.W. I smiled all the while I was outside in the sunshine
Over educated idiots always make me smile.
Excuse me for bieng sort of off topic here.
 
Hey, I’m one of those idiots. /bcforum/images/%%GRAEMLIN_URL%%/thumbsup.gif

Yeah, a lot of things get done for no reason other than inertia. Then again, sometimes there are very subtle technical reasons for doing something a certain way. Without asking the originator of the procedure you don’t really know.

I’ve seen plenty of stupid things that were done out of haste, misinformation, cluelessness, or expediency. But the history books are also filled with tragic tales of people who ignored a technical detail because they didn’t understand or agree with it only to find out the hard way that it was actually critical.

I’ve always been a firm believer in questioning everything. If there was a good reason for it you should be able to find it. If you don’t maybe it’s time to carefully study how it really works and either keep it or change it based on your findings.
