    Unrealistic roughness coefficient could impair pipe capacity

    19/2/2016· Design engineers must keep in mind that the Manning formula, developed in 1890, is an empirical relationship with a roughness coefficient n Value that actually varies with pipe size, slope of the pipe, and flow depth. Engineers must also recognize that the Manning’s n Value of 0.009 is derived from laboratory studies that examined small pipe sizes, or is based on clean water flowing through Puhui Pipe manufacturer in China
