Does anybody know the relationship between the air's viscosity and the pressure(0.1 to 10000 times of the atmosphere pressure)? Thanks a lot!!

Look in Bird, Stewart, & Lightfoot, "Transport Phenomena". There's a correlation for monotomic gases (use nitrogen).

Also look in Perry's Chemical Engineer's handbook. I think there's a correlation in there for air as well.

I don't have access to these books, can you post the correlation you found (if any)? I need viscosity vs. temp and pressure relationships for high pressure air.
