Q = pipe capacity, cfs n = Mannings n (unitless), a term used to describe material roughness A = cross-sectional flow area of the pipe (ft2) R = hydraulic radius (ft), 1/4 the diameter for full-flowing pipe conditions S = pipe slope (feet/foot) Equation 1(a) Q = AR2/3 S1/2 n Where Q = pipe capacity (m3/s) n = Manning n (unitless) Is the Manning equation used to partially fill circular pipes?Is the Manning equation used to partially fill circular pipes?From engineeringexceltemplates, Manning Equation Partially Filled Circular Pipes The Manning equation was developed for flow in open channels with rectangular, trapezoidal, and similar cross-sections.Circular Pipe Mannings n Plainwater What is the n value of concrete pipe?What is the n value of concrete pipe?Concrete pipe with poor joints and deteriorated walls may have n values of 0.014 to 0.018. Corrugated metal pipe with joint and wall problems may also have higher n values, and in addition, may experience shape changes which could adversely effect the general hydraulic characteristics of the pipeline.Circular Pipe Mannings n Plainwater
