The pipe diameter is 800mm. The ultrasonic measurements recorded are: Pipe centerline velocity = 4.9 m/s %3D Velocity at radius 100mm = 4.4 m/s %3D Solve for the Friction factor f using turbulent flow profile.

For the selection of friction factor, f from the Moody diagram, select the most appropriate answer. O For smooth-walled pipes, we need to know Re only. O All the answers are correct. O For laminar flow, we need to know Re only. O For rough turbulent flow, we need to know Re vs ks/D.
