3.6.2 aude_q - Aude volume flow Q
q = aude_q(p,d,v,k,sg=1)

Calculates the volume flow Q given a pressure drop due to friction P using Aude’s equation.

Arguments

p

Pressure drop due to friction (kPa/km  ).

d

Pipe internal diameter (m  ).

v

Liquid viscosity, centipoise.

k

Pipe roughness/efficiency k ∈[0.90,0.95]  .

sg

Liquid specific gravity.

Returns Volumetric flow rate (m3/h  ).

Possible Warnings

Aude roughness factor out of the nominal range

The provided roughness factor is not within k ̸∈[0.90,0.95]
