RE: [TCML] How much CFM is needed for an RQSG on a 12/60 powered coil?

["Aron Koscho" <kc5uto@xxxxxx>]

I always used the biggest one I could get; typically ~180cfm.

Hi Vinnie,
 
I think you have asked one of the quantitatively least-studied Tesla
coil  
related questions. I think the best information you will get is someone
saying  
"I used this size and I've had no problems yet." You will then have to
guess 
how  closely your gap resembles theirs. An analytical answer would
depend on 
the  shape, size, material and orientation of each component of your gap
well as 
the  ambient conditions, as it involves conduction, convection, and
radiation 
in  three dimensions, where the energy being dissipated can only be 
estimated, and  the properties of the materials change with time and
oxidation - not a  
trivial thermodynamics problem. This is still in the "cut and try" state
of 
the  art.

Hi  Guys

I'm building a new RQSG and want to use a muffin fan rather than a
vacuum 
or blower. I was wondering if anyone knows how much air flow I  might
need 
for this?
