Hazen Williams Coefficient

The following values are used in the Hazen Williams Equation. The lower the coefficient, the smoother the pipe is. The higher the coefficient, the less fluid flow is restricted. By using pipe materials with improved flow characteristics, energy costs for pumping can be reduced or smaller pipes can be used.
