Homework Help: Finding velocity

  1. Apr 15, 2010 #1
    1. The problem statement, all variables and given/known data

    If the fluid water with kinematic viscosity v=1 x 10^-6 m^2/s and density of 1000 kg/m^3, determine the Max velocity V that an upper plate could be moved to produce a laminar, linear, flow distribution when the height is 3 mm. The limiting Reynolds number for a laminar linear velocity profile is Re = 200.(Recall that the Reynolds number is formed using average flow velocity)

    2. Relevant equations

    Re = average velocity x height/kinematic viscosity
    Shear Stress(T)= dynamic viscosity x Velocity of plate/height
    Average velocity = area under profile/flow depth

    3. The attempt at a solution

    I have been able to solve for the Reynolds number, but I am not sure what to do after.
