I am looking at the concept of Reynold's number applying to anesthesia circuits. I understand that one formulation for Reynold's number as it relates to a fluid flowing through a tube of constant dimensions is:

R# = (Velocity x Diameter x Density)/Viscocity

I know that a high R# is characteristic of turbulent flow. I also understand that increasing the diameter of a tube should promote laminar flow through it, how do I reconcile that with the Diameter term being in the numerator (thus increasing the R#, which should promote turbulent flow)?

I did not see this specific questions addressed in other R# threads. If so, sorry for the redundancy.
