| Abstract | Experimental determinations have shown that the resistance factors for conduits manufactured of corrugated metal vary over a wide range for each of the different corrugation forms now available. Hydraulic design procedures require a reliable determination of the resistance factor applicable to each specific form. Methods are developed, using all available data, whereby such resistance factors can be determined within close tolerances in terms of either the Darcy f or the Manning n. Variables considered include conduit size and shape, corrugation form, flow rate, and flow depth. Design charts and geometric tables are presented for the commonly available conduits of five corrugation forms, and examples illustrating use of the charts and procedures are given. |
