Re: Kestrel Wind tunnel data [MITaerobike]

--- Nope, I subtract tares so that the raw corrected values are representative of real world drag values that can be used when comparing to power testing. I don't have an apparatus mounted to my bike when I do power testing, so I don't include that drag.

Yeah...I was thinking the same thing when Carl made that comment...why wouldn't you want to subtract the tare. That would make it slightly easier to compare across tunnels too, right?

We publish in grams of force because people like seeing that.

I think it's time to start changing that paradigm and publish in CdA (m^2) as the primary "units" ...and just give "grams @ 30mph, STP, etc." as a reference :-)

I study in CdA (m^2) and want all of my wind tunnel data to be useable for real world simulations.

Amen...but, does that mean you've convinced the A2 folks to report CdA in m^2 instead of ft^2 ;-)
