KRAH - Hydraulic calculation of PE pressure pipes

Krah pipes are often used for pressure applications, whether the requested pipe material is a standard High Density Polyethylene (HDPE) or Polyethylene reinforced with glass fibres (PE-GF). For the flow-characteristic and pressure loss the surface quality is essential, since the surface-roughness affects the friction between fluid and pipe wall.Manning's "n" For PVC Gravity Sewer Pipe - Diamond PlasticsJan 12, 2017Some specifications still require that "n" = 0.013 for the design of all sewer pipes. The reasoning is that all sewer pipes will even­tually build up a layer of slime, so all pipe materials should use the same coefficient. However, research has shown that the thickness of the slime layer varies with the pipe material's roughness and porosity.Mannings n Roughness Coefficients - Closed Conduits hdpe pipes roughness in botswanaThe following Mannings n Roughness Coefficient table is from the United States Department of Transportation Federal Highway hdpe pipes roughness in botswana Corrugated metal pipe or pipe-arch Corrugated Metal Pipes and Boxes, Annular or Helical Pipe (Manning's n varies with barrel size) 68 by 13 mm (2-2/3 x 1/2 in.) corrugations. 0.022-0.027. 150 by 25 mm (6 x 1 in hdpe pipes roughness in botswana
