Consider laminar flow in a circular tube. Will the friction factor be higher near the inlet of the tube or near the exit? Why? What would your response be if the flow were turbulent?
What will be an ideal response?
The friction factor is highest at the tube inlet where the thickness of the boundary layer is zero, and decreases gradually to thefully developed value. The same is true for turbulent flow.
