Hi justjohn,
I have a recollection of a table of shapes and their drag coefficients. I'm thinking it was Eshbach or someting in the Wiley series. Anyway, I think the table had all the usual suspects; flat plate, hemisphere, cone... but also a couple of mesh sizes too. I'm sure the drag on hardware cloth was about 4 or 5 times a flat plate. Have you seen a table like that?

I have no idea what the real answers to these questions are, I'm just saying I don't think you can make those kinds of assumptions. I will see if I can come up with any research on it.
