friction head

Accordingly, the relationship between the friction head and the Fanning friction factor is:

Resistance head (or friction head or Head Loss) is due to the frictional forces acting against a fluid's motion by the container.

The friction head can be related to the pressure loss due to friction by dividing the pressure loss by the product of the acceleration due to gravity and the density of the fluid.

Handle systems of any size Compute friction head loss using the Hazen-Williams, the Darcy Weisbach, or the Chezy-Manning head loss formula Include minor head losses for bends, fittings, etc.
