Calculating Friction Loss - PM Engineer

10/4/2006· As with the Darcy-Weisbach formula, the internal roughness of the piping, flow of water, velocity and hydraulic slope are taken into consideration during the calculation of friction loss. However, the Hazen-Williams formula was not revised to take into consideration different viscosities of liquids like the Darcy-Weisbach formula does during the calculation of the Reynolds Nuer.


Friction Loss is considered as a “major loss”. “Head” is a very convenient term in the pumping business. Pressure is not as convenient a term because the amount of pressure that the pump will deliver is dependent upon the weight (specific gravity) of the liquid being pumped and as you know, the specific gravity changes with the fluid temperature and concentration.

Darcy–Weisbach equation - Wikipedia

In fluid dynamics, the Darcy–Weisbach equation is an empirical equation, which relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. The Darcy–Weisbach equation contains a
