Friction coefficients of pipes
Large sewer systems and culverts
use concrete and steel pipes to drain storm or wastewater from urban
areas and away from roadways. Basic principles and engineering issues of the design and construction of these pipes are referenced in numerous handbooks. The mostly gravity driven flow in the pipes is resisted by wall friction. Friction coefficients are used to relate head loss from wall friction
to the length, diameter, roughness, and the mean flow velocity in the pipe. Head losses and velocity distributions were measured using water diverted from the Mississippi River and friction coefficients were determined for large helically corrugated metal pipe. [17,18]
