"WebDec 21, 2015 · In turbulent flow the friction is inertial for the most part: the chaotic flow causes the fluid in the faster moving center to interchange randomly with the fluid near the edge. This eventually allows momentum from the center to be transferred to the walls of the pipe (i.e. friction). " - Fluid flow patterns physics
