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  .
