The velocity field for a line vortex in the r-plane (Fig. P443) is given by u r

The velocity field for a line vortex in the rθ-plane (Fig. P4–43) is given by u_r = 0 u_θ = K/r where K is the line vortex strength. For the case with K = 1.5 m/s², plot a contour plot of velocity magnitude (speed). Specifically, draw curves of constant speed V = 0.5, 1.0, 1.5, 2.0, and 2.5 m/s. Be sure to label these speeds on your plot.
