The hydraulic roughness of 200-mm, 250-mm, and 300-mm corrugated plastic drainage pipe was measured. The Darcy-Weisbach friction factor and the Manning roughness factor respectively are, as follows: 200 = 0.082 and 0.019; 250 mm = 0.068 and 0.018; and 300 mm = 0.095 and 0.022. A graph for pipe diameter selection for a choice of slopes is included.
