Flow Velocity- Guranteed to be Laminar

  1. Oct 10, 2012 #1
    I am absolutely stumped on this last question for my assignment, I have no idea what to or how to calculate the flow from just these given constants.

    Q) Water (p = 998 kg/m^3
    , n = 1.0*10^-3 Pa.s at 20C) at 20C flows through a pipe of
    diameter 50.0 mm. What is the maximum average flow velocity if the flow is
    guaranteed to be laminar? Give your answer in mm/s.

    You have to decide a limiting Reynolds number for laminar flow and apply the formula that relates to a tube. If you've had a course this question must be pretty close to it.
