Linear Length Pipe Loss Calculator

One of the most renowned methods of pipe loss calculation is by using the Hazen-Williams equation, especially when the fluid involved is water.

The equation estimates the frictional loss (feet) for a specific pipe with Length, L (feet), Diameter, D (inch), Flowrate, Q (usgpm) and C-value, Hazen-Williams coefficient, C.

The C-value of different materials of pipes can be referenced from various sources, summarized below. The higher the C-value, the “smoother” the flow is in the pipe.
