Water enters a 13-cm-diameter pipe steadily with a uniform velocity of 2 m/s and exits with the turbulent flow velocity distribution given by u = umax(1 − rR)1/7 . If the pressure drop along the pipe is 10 kPa, determine the viscous force exerted in the pipe by the water flow. Take the density of water to be 1000 kg/m3. The average velocity is equal to 0.816 times the max velocity. The viscous force exerted in the pipe by the water flow is 50
