Bombardelli 1 and Marcelo H. Garcı ́a, M 2. Abstract: The Hazen–Williams formula is frequently used for the design of large-diameter pipes, without regard for its limited range of applicability. This practice can have very detrimental effects on pipe design, and could potentially lead to litigation.
