The change from stream-line to eddy motion in water was first examined by Osborne Reynolds, who in his earlier experiments, introduced colour-bands into a glass pipe in which water was flowing, to indicate the change in the motion, and later observed the resistance encountered in pipes over a great range of velocities. The results of these experiments, and a consideration of the equations of motion, enabled him to express the laws relating to the critical velocity of water in pipes by the exceedingly simple equation v c = k μ/rρ where v c is the critical velocity of water, r is the radius of the pipe, μ is the viscosity of the water, ρ is the density, and k is some constant.
