The Hazen Williams formula is an empirical equation that can be used to calculate the pressure loss per one foot of pipe of a known diameter due to friction dependent on the flow. Here we can calculate for Discharge or Fluid Flow Rate, Friction Coefficient, Pipe Diameter, Hydraulic Grade Line Slope.
