Section A
(a) The water flows steadily through a pipe of length L and radius R = 75 mm. The velocity distribution across the outlet is given by (u)/(U_{\textmax}) = 1 - (r3)/(R3) The value of U_{\textmax} = 3 m/s. The inlet velocity is uniform and expressed as U. Find the net rate of volumetric flow out from the outlet control surface (m3/s) and the value of U (m/s).
