I must have given reference values already. www1.grc.nasa.gov/beginners-guide-to-aeronautics/drag-of-a-sphere/ has detailed discussion of the problem. The plot at the top of the page gives Cd as a function of Reynold's number. I hope this will address your question.
CD = 0.007? Something is wrong. It should be close to 0.50 for a sphere, according several available sources. Please clarify, Thank you.
I hope "www1.grc.nasa.gov/beginners-guide-to-aeronautics/drag-of-a-sphere/" has detailed explanation.
Is drag coefficient 0.007 correct value ?
not for a sphere
What are your reference values?
