Cd-data for a sphere
Hello World.

Does anybody have digital (tabulated) data for the drag coefficients of a sphere?
I'm searching for the Cd-over-Re-curve in some kind of processable form.
This maybe Excel, MATLAB or simple ASCII-form.

Anything I have found so far is in graphical form like the one below.

Thanks so far!
Have a nice day.

This is great! Thank you!
Does anyone have this kind of data for dimpled balls?
Or can tell me at which Reynolds number the transition laminar-turbulent will occur?
