How do you figure what your coefficient of drag is?

Scott

Pay your bucks to the wind tunnel or do a roll down test.  I believe Jack D has experience in doing roll down tests.

I would have to dust off a book or two or do a bit of googling, so you may see what you can find on roll down tests.  In theory it's supposed to be easy IIRC.

Uh, see "Coast Down Formula", in "Formulas", this site.

Jack started his tests at the local bowling alley -- and progressed to engineering wonders.

Hello, I just went to open the nomograph, one of my favorite things, and it appears the link is broken. Is there another way I can get access to it?
Thanks, Ralph Hudson

I was wondering the same thing?

Is there another calculator to use that has the cd numbers?

I suspect this may be an issue the web elf needs to sort out, the link might have gotten broken when they did the upgrade.
