3.5.3 hazen_williams_c - Hazen-Williams roughness factor

q = hazen_williams_c(p,q,d,sg=1)

Calculate the Hazen-Williams roughness factor from the pressure loss due to friction and the volume flow.

Arguments

p

Pressure drop due to friction ().

q

Volumetric flow rate ().

d

Pipe internal diameter ().

sg

Liquid specific gravity .

Returns Roughness factor of the pipe , see table 3.5.1 for usual values.

Possible Warnings

Hazen-Williams calculated factor appears to be invalid

The Hazen-Williams factor that was calculated is not plausible.
