WebThe Hazen-Williams equation is most accurate for flow velocities between 3 to 10 ft/s (0.9 to 3 m/s) and may yield inaccurate results outside this range. Similar to the Darcy-Weisbach equation, the Hazen-Williams equation does not account for minor losses due to pipe fittings and valves. WebAside from the main Matlab tool, two other converter tools are also given to obtain the Hazen-Williams roughness coefficient C as a non-steady variable by a function of (i) the absolute roughness of the pipe (also known as ε - eps) …
