Velocity Profile

  1. Nov 17, 2012 #1
    What is a velocity profile in fluid mechanics? Why do they give you a ratio between the fluids velocity and a random reference velocity and why is it equal to a completely arbitrary function?
    Does the ratio equal a function because it is an experimental fact?

    Can you give a specific example of what is troubling you? It is difficult to understand your question otherwise.
