Web10 okt. 2015 · So the radius, or the diameter, are a good choices for the characteristic length. Obviously Re will be different (by a factor of 2) if you choose the radius or the diameter, so in practice everybody makes the same choice and everybody uses the same critical value of Re for the transition from laminar to turbulent flow.
