WebThe roughness of the pipe surface influences neither the fluid flow nor the friction loss. In turbulent flow, losses are proportional to the square of the fluid velocity, V2; here, a layer of chaotic eddies and vortices near the pipe surface, called the viscous sub-layer, forms the transition to the bulk flow.
