The streamlines of a potential line vortex is concentric circles with respect to the vortex center as shown in figure. Velocity along these streamlines, outside the core of the vortex can be written as, vθ=Γ/(2πr), where strength of the vortex is Γ/(2π) and r is radial direction. The value of circulation along the curve shown in the figure is:
