FRICTION FACTORS FOR HYDRAULIC DESIGN OF CORRUGATED METAL PIPE
RESULTS OF MODEL TESTS OF TWO TYPES OF CORRUGATED METAL PIPE INCLUDING FRICTION FACTOR-REYNOLDS NUMBER DIAGRAMS AND MEAN FLOW FORMULAS DEVELOPED FROM VELOCITY DISTRIBUTION DATA ARE REPORTED. CALCULATED MAXIMUM VALUES OF THE FRICTION FACTOR DUE TO THE CORRUGATIONS AND THE BOLT NUTS ON THE CRESTS OF THE STRUCTURAL PLATE CORRUGATIONS FOR VARIOUS SIZES OF EACH TYPE OF PIPE ARE COMPARED WITH THOSE OF SIMILAR PROTOTYPES AS REPORTED BY OTHER INVESTIGATORS. RECOMMENDED DESIGN VALUES OF THE FRICTION FACTOR FOR ANNUAL CORRUGATED PIPES WITH CORRUGATION DEPTH-SPACING RATIOS OF 1'3 AND 1'5.33 ARE RELATED TO DIAMETER, AND SIMPLE EMPIRICAL EQUATIONS DESCRIBING THE RELATIONS ARE DEVELOPED. /AUTHOR/
