Figure 1 below shows a pipe of length L, (with L >>D) and with viscous flow inside. The flow is fully developed

at the exit plane. The velocity distribution at the inlet is uniform. At the exit plane, only the shape of the velocity

distribution is illustrated: the magnitudes are not to scale. What should be the magnitude of the maximum

velocity at the centerline of the exit plane, v_2,max?
