There are Hazen-Williams constants in CERM A-25. However they are over much wider range. I answered a sample qetion using A-25 and was wrong because the top value was 150, I assumed for a new pipe the max would apply, the answer was 130 as the table shows.Hazen-Williams Equation and roughness constant
