To my knowledge a pitot tube pressure/speed chart isn't based on a
certain diameter tube . May-be that's not the best example but it makes me
think that impact pressure is a constant and a low CD shape just has a
smaller percentage of the frontal area that sees the full impact pressure .

John;
I don't think so but I wouldn't bet money on it. Think of a symmetrical
wing-- the peak pressure is on the leading edge; on a wedge- shaped
airfoil with the pointy end forward..........

Do you agree that at a given speed all body shapes have the same peak
pressure at some point ?
