3.8.5 oliphant_q - Oliphant for flow Q
q = oliphant_q(type,l,d,p1,p2,pb,tb,tf,sg=1)

Calculate the volume flow Q using the Oliphant equation.

Arguments

l

Length of the pipe L (m).

d

Diameter of the pipe D (m).

p1

Upstream pressure P1 (kPa ).

p2

Downstream pressure P2 (kPa ).

pb

Base pressure Pb (kPa ).

tb

Base temperature Tb (K).

tf

Average temperature Tf (K).

sg

Gas gravity (gair= 1).

Returns Volume flow Q in m3/h.
