Think about the Source & Sink again, and now imagine that you are looking at this flow pattern from very far away. The streamlines that are between the source and the sink will be very short, from this vantage point. And the other streamlines will start looking like two groups of circles, tangent at the…

In accord with Stockes’ teorem, this line integral is equal to the flux through the contour of the curl of velocity, which is the vorticity, ω=∇×v: If the vorticity is zero (irrotational flow), so is the circulation around any closed contour equal to…
