Laminar and Turbulent Flow in TubesFor flow in a circular tube, the Reynolds number is defined as

For flow through noncircular tubes D is replaced by the hydraulic diameter Dh.

laminar flow: Re10,000.

Reynolds Analogy for turbulent flows through tubesSimilar to Reynolds Analogy for laminar flow over a flat pipe.
