aude_p - Aude pressure drop for P

3.6.1 aude_p - Aude pressure drop for $P$

p = aude_p(q,d,v,sg,k)

Calculates the pressure drop across a pipe using Aude’s equation for petroleum products. The equation is valid for pipe sizes 8"-12" ( 200-300mm) in diameter for crude oil with Reynolds numbers $[6000,120000]$ and 6"-8" for Reynolds numbers $≥57000$ for refined products.

Arguments

q: Volumetric flow rate ( $m3/h$ ).
d: Pipe internal diameter ( $m$ ).
v: Liquid viscosity, centipoise.
k: Pipe roughness/efficiency $k ∈[0.90,0.95]$ .
sg: Liquid specific gravity.

Returns Pressure drop due to friction ( $kPa/km$ ).

Possible Warnings

Aude roughness factor out of the nominal range: The provided roughness factor is not within $k ̸∈[0.90,0.95]$
