    How was the first part answered, and does one see any relevancy to the subsequent questions?

    For a two-dimensional incompressible flow in the x,y plane, the conservation of mass (continuity) equation can be written as,

    [tex]\frac{\partial u}{\partial x}\,+\,\frac{\partial v}{\partial y} = 0[/tex]

    and since the flow is rotational,

    [tex]\nabla\times\nabla\phi\,\neq\,0[/tex]

    where [itex]\phi[/itex] = velocity potential.
