Pipeline pressure losses are calculated
for each segment of the piping network using standard
pressure loss correlations. GASMAN utilises a
frictional-loss pipeline and the Churchill friction factor
to calculate pressure losses in pipes due to friction and
elevation.
The pressure loss will normally be calculated for a single
gaseous phase with corrections for water gas ratio (WGR) and
condensate gas ratios (CGR), which will be defined by the
user.
The pressure-loss calculations are based on single-phase
analysis, condensate and water quantities. Their respective
volumes are then determined at the main separators and
tracked throughout the gathering system.
The pipeline pressure-loss software also includes standard
correlations for pseudo two-phase and two-phase fluids such
as Grays correlation. |
