You can find out more information about the Hazen-Williams pressure loss equation. Then using the calculator please remember to use the internal diameter of the pipe and not the nominal otherwise the answer will not be valid. So the pressure is in bar, flow in Litre per minute (L/min) the internal pipe diameter (ID) is in millimetres (mm). The equation which we have used is based on the equation in EN 12845, NFPA 13 and NFPA 750 and uses the metric units. The Hazen-Williams pressure loss equation is used throughout the world for calculating the pressure loss in fire sprinkler systems, wet risers, fire hydrant systems and many other types of fire protection systems including low-pressure water mist.īellow, you will find an online Hazen-Williams calculator which you can use to calculate the pressure loss in a pipe using the Hazen Williams pressure loss equation.
