Operating Pressure and Cd
 
I notice that if I change the operating pressure it affects the results I get for the drag coefficient. My sources tell me that should not be the case.

I do not understand enough to know why not.

If Cd should be independent of Operating pressure -- any suggestions as to what may be the cause?

thanks!
