Homework Help: Velocity and Vorticity of a Tornado Calculation

  1. Jan 10, 2013 #1
    1. The problem statement, all variables and given/known data

    A tornado:

    of d = 2r = 0.9 km

    r = radius

    vortic ity 9 rad/s at altitude 0.8 km

    What is the velocity at ground level given 2*pi*r = 95 m at that level.

    If someone could just guide me on what the relevant equations are. I am revisiting the background material but any insight is appreciated.
