 October 24, 2000, 20:33 Nondimensionlization on Parallel-plate #1 Juhee Lee Guest   Posts: n/a It is well known the solution of the flow between flat-plates(infinitive plate); u=0.5*Re*(dp/dx)(y^2-h^2). Here,h is for half-length of the height between plates. The problem is what is the reference velocity.If the Re=10, and dp/dx=0.01, max velocity is 0.1. Here, I wonder the meaning of the max velocity. I'd like to use Uavg(=Q/A) as reference velocity. How can I do that? Thanks ahead.
