This friction loss calculator employs the Hazen-Williams equation to calculate the pressure or friction loss in pipes. Losses are calculated on the basis of flow rates in circular pipes, the internal diameter of the pipe, the length of the pipe, and the type of pipe

### Friction loss - Wikipedia

In fluid flow, friction loss (or skin friction) is the loss of pressure or head that occurs in pipe or duct flow due to the effect of the fluid's viscosity near the surface of the pipe or duct. In mechanical systems such as internal combustion engines, the term refers to the power lost in overcoming the friction between two moving surfaces, a different phenomenon.
