WebHowever, the Manning Formula applies to open channels or partially filled pipes, rather than fully filled pipes. Also like the Hazen-Williams equation, it does not require a friction factor to quantify the relationship between velocity and head loss. Therefore, it is not necessary to use the Colebrook equation with Manning’s equation. WebHead loss calculations are based on equations developed by hydraulic engineers who conducted numerous flow tests on in-service water mains. Several formulas were developed by Darcy, Chezy, Cutter, Manning, Hazen-Williams, and others. Of these, the formula developed by Hazen-Williams has proven to be the most popular.
