Model investigations were conducted in test sections simulating 5-, 10-, and 20-ft-diameter pipes, and the data obtained on hydraulic gradients, velocity distributions, and static pressure measurements were used to develop a mean flow equation with which the resistance coefficients due to the corrugations for all sizes of structural plate pipe can be computed. A method for determining the increment of resistance attributable to the assembly bolts of structural plate pipe is presented. In addition, empirical equations are developed that enable determination of the maximum values of the Darcy-Weisback f and the Mannings n for any diameter of corrugated pipe of the common structural plate and standard varieties as well as the relatively new type with annular 1- by 3-in. corrugations.
