Ehsan Sadeghi I'm not quite sure what you mean. Are you suggesting than in the equation to calculate the Reynolds number

(v x L x rho)/(mu)

that I take my average axial velocity as v and my diameter as L?

Also, do you have any suggestions for what the critical Reynolds number or transition range would be, given this is external flow?

Thank you
