The velocity field for a line source in the rθ-plane (Fig. P4–44) is given by

where m is the line source strength. For the case with m/(2π) = 1.5 m²/s, 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.
