4. Problem 4-42: The velocity field for solid-body rotation in the re-plane (Fig. P4-42) is given by u, = 0 ue = wr Where w is the magnitude of the angular velocity (@ points in the z-direction). For the case with w = 1.5 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. FIGURE P4-42
