q = hazen_williams_q(p,d,c,sg=1)
Calculate the Hazen-Williams volumetric flow rate given the pressure drop due to friction. Common values for the roughness factor of the pipe by material are provided in the in table 3.5.1.
Pressure drop due to friction ().
Pipe internal diameter ().
Roughness factor of the pipe , see table 3.5.1.
Liquid specific gravity .
Returns Volumetric flow rate ().
A negative or zero Hazen-Williams factor was supplied.
