The flow of glycerin (kinematic viscosity v = 5 ×10-4 m2/s) in an open channel is to be modeled in a laboratory flume using water (v=10-6m2/s) as the flowing fluid. If both gravity and viscosity are important, what should be the length scale (i.e. ratio of prototype to model dimensions) for maintaining dynamic similarity ?
