Hi,

I've been reading up a little on the Reynolds Number Rn, and I don't really understand how to use it. Would one of you geniuses please fill me in a little? I know how to calculate it, but what do you do with it? I know it will change with airspeed, but what makes a good Rn vs a bad Rn? I'll probably have more questions later.

Thanks in advance,
Soj
