4.3 Volume Flow at Line Conditions
The volume flow at line conditions Q
Line
is the (adjusted) profile-corrected
gas velocity V
line
multiplied by the internal cross section A of the flow cell:
where:
Q
Line
the volume flow at line conditions
V
line
the adjusted profile-corrected gas velocity
D the internal diameter of the meter
A the internal cross-section of the flow cell
t time coefficient to go from seconds to hours.
