Reply to "Nitrogen in tires?"

If I am starting out at 35psi at 70F, and the temperature drops to 15F and I wind up with say 15psi that is measurable, can I calculate the amount of water that was in the air in the tire?

Sounds like I am pumping quite a bit of water vapor into these tires at 70F?

How much of that can be removed by purging and running the compressed air through a good desiccant or better yet do I need to contrive a desiccant filter system to remove a specific amount of compressed water vapor?

Should that filter be on the intake of the compressor or the exhaust or both?

Do I need to have a proportional desiccant filter size relative to the intake or exhaust of the compressor to achieve this?

Are there better substances that work as a desiccant than others?


I can see that in many instances it may be much simpler to drag around tanks of very dry nitrogen to the race track or out onto the runway to top the tires rather than have an extravagant air drying system on a small portable compressor?

That isn't a stretch to see that as a player in using nitrogen in race cars rather than very dry compressed air, i.e., nitrogen in a bottle is actually a whole lot easier to use than drying out the compressed air in a remote location?



Also, not a scuba diver here but is the amount of water vapor that is compressed into a scuba tank a consideration too?

Are you changing the safety of the breathen air to the diver by doing that or better yet shortening the life expectancy of very active scuba divers by making them breath an unnatural mixture for extended periods of time?

Any MD's here care to comment on that one? Not being paranoid here folks. I blame this all on Ray Herbert, aka, Mr.Wizrd. He ruined me for life? There wasn't anything else on tv on Sunday afternoon here. Giant home games were blacked out then. You basically only could see them play the Cowboys away on TV.



Ever walk down a straight expansion line in the sidewalk? Is it better to walk in a natural rhythm of one foot starting on one side of the
line and varying with the other?

What happens if you skip on one foot and vary the pattern? Is this the difference between sanity and insanity? OMG! I just answered my own question! Someone please help me! roll on floor
