spitzglass_q - Spitzglass for flow Q

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

Calculate the volume flow $Q$ using the Spitzglass equation.

Arguments

type

Pressure drop type, this can be either of:

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.

sg

Gas gravity ( $gair= 1$ ).

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