@RobotechMacrossGame Yes, i ment C_D.

@SlavaVB It depends on the Reynolds number. For a sphere there's a
range in R, where the drag is minimum (drag crisis regime)

what's the music? :)

Actually, it probably is, when the flow is separated the drag increases and turbulent flow separates later than laminar flow would. That's why golf balls have dimples, to make the flow turbulent.

doesnt it seem as if the turbulence is actually reducing the drag here?
