The velocity profile in fully developed laminar flow in a circular pipe of inner radius r = 7 cm, in m/s, is given by u(r) = 4 (1 − r2r2). determine the average and maximum velocities in the pipe and the volume flow rate. (round the final answers of the velocities to two decimal places and the final answer of the volume flow rate to five decimal places.)
