3. a rankine vortex contains a viscous core surrounded by an irrotational free vortex. a piecewise equation for the velocity in a rankine vortex is uθ = γr/(2πr^2) for r ≤ r, and uθ = γ/(2πr) for r > r. ur = 0 everywhere.
a) compute the circulation around a circle of r ≤ r using the flow velocity.
b) compute the circulation around a circle of r ≤ r using the flow vorticity
c) compute the circulation around a circle of r > r using the flow velocity.
d) compute the circulation around a circle of r > r using the flow vorticity.
