Full Description

A brief review is made of the theory of roughness, of the test results on which the recommended roughness values were based, and of various exponential formulas in common use in the U.S. A table of recommended values of the Hazen-Williams coefficient C, based on a close comparison with the theory of roughness, is presented . Carrying capacities of cast iron, steel, concrete, cement-lined, plastic, and asbestos-cement pipe are covered. Includes tables, figures, appendices.
