Paul,
    I think you would be a good one for this question. is there a formula to
figure out the amount of air pressure comming in the  frontal area of a
venturu, what it would be at the base.i.e.. at 100mph a given sq.in. area
would give you  x at the intake and at the base of the ventury it would be
'y' for a given diameter. I included a rough drawing, very rough, if it
helps. Also I asked you about 3d cad programs, you suggested Rhino, do you
know how that might compare to Mastercam solids?
Thanks,
Richard Konnen

There should be some formulas around for venturi someplace.

I have never used Mastercam. I have version 9. My main
interest would be not to design with it but use it to generate
G codes for NC machines. I assme it does that.
