Irodov Problem 1.337

The Reynold's number for a sphere of radius r1 falling through a fluid of density at a velocity v1, is given by . Since at velocity v1 the flow starts to become turbulent, this is the Reynold's number corresponding to turbulent flow. For the other fluid the flow must become turbulent at the same Reynold's number. So we have,
