RM2 airhole size

[Matthee]

Now . . . . how is a person to take this little comment?

Hah, gotcha there Pdib, no retort for once! Obviously just poking fun. But, am afraid with eHuman's scientific post above you have just being dethroned!

Along with what JC Okie said, keep in mind: When you double the size (diameter) of a hole (circle) you roughly quadruple the area. So you are not doubling the airflow volume your are quadrupling it.

Area of a circle = pi*r²
(Baseline diameter of "1" units) = 3.14*.5² = .79 area
(Increase to diameter of "2" units) = 3.14*1² = 3.14 area
(Increase to diameter of "4" units) = 3.14*2² = 12.57 area

If you don't know your sweet spot, increase in increments or you will exponentially increase air flow and risk ending up with a cap you don't want to use.

If you have a stainless steel corkscrew, put it in the air hole (both from inside and the outside) and bobble it around to open up the air flow a little at a time. This is especially useful if you don't happen to have a nice drill bit index, and it works on SS rba caps too.

Ummmm WOW! I have no idea if any of that is correct but WOW! lol And this just proves REOnauts are the smartest people on the internet. Well not me per say but I get elevated due to proximity.

I guess I should add something useful and say my air holes on the grands are 1/16'' running about .9 to 1.1ohms and the mini is stock running 1.4 ohms.

dang. nobody told me when i first started vaping that there'd be math.

is that gonna be on the final?

You guys rock. Endless interesting comments on every subject. What I am gonna come up with next? Hmmm....
As for my airhole I had figured the exponential enlargement and that is what got me worried. I'm gonna go with "don't enlarge if it is not consistently too intense". And in fact it is not right now. My descent into low ohms might not be finished though, as I hate taking endless drags.
Thanks again reoville!
