3.8.6 igt_q - IGT for flow $Q$

q = igt_q(l,d,p1,p2,pb,tb,tf,z,e,mu,sg=1)

Calculate the volume flow $Q$ using the IGT 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 $Tf$ ( $◦K$ ).
z: Gas compressebility factor.
e: Pipeline efficiency factor.
mu: Average viscosity in the pipeline ( $Pa·s$ ).
sg: Gas gravity ( $gair= 1$ ).

Returns Volume flow $Q$ in $m3/h$ .
