Column Headings Description
Finish Inv. This column contains the finish invert elevation for the pipe segment. This value is also
the invert in elevation of the next node. The finish invert elevation is calculated from the
starting invert elevation using the pipe length and slope. Changing the slope changes
the finish invert elevation as well as all invert elevations downstream of the finish invert.
Invert elevations are changed by editing the slopes, node drops, or the first starting
invert. When an invert elevation changes, all downstream invert elevations are updated
based on the slope and node drop values. The starting invert elevation also changes if
you enter a lateral that has an invert elevation lower than the previous finish invert
elevation. The upstream invert elevation also affects the invert elevation values.
Flow Regime This column contains the flow regime designation of critical, subcritical, or supercritical.
Froude Number This column contains the Froude number for the pipe segment.
Full Area This column contains the full-flow wetted cross-section area value for the pipe segment.
This value is determined based on the current pipe configuration and flow calculation
formula. You can make your own full-flow wetted cross-section area calculations if
necessary. Place your cursor in the Full Area column and click Edit to open the
appropriate Pipe Calculator dialog box.
Full Flow This column contains the full-flow value for the pipe segment. This value is determined
based on the current pipe configuration and flow calculation formula. You can make
your own full-flow calculations, if necessary. Place your cursor in the Full Flow column
and click Edit to open the appropriate Pipe Calculator dialog box.
Full Perim This column contains the full-flow wetted perimeter value for the pipe segment. This
value is determined based on the current pipe configuration and flow calculation
formula. You can make your own full-flow wetted perimeter calculations, if necessary.
Place your cursor in the Full Perim column and click Edit to open the appropriate Pipe
Calculator dialog box.
Full Vel This column contains the full-flow velocity value for the pipe segment. This value is
determined based on the current pipe configuration and flow calculation formula. You
can make your own full-flow velocity calculations, if necessary. Place your cursor in the
Full Vel column and click Edit to open the appropriate Pipe Calculator dialog box.
HGL Elev In This column contains the hydraulic grade line elevation in value, which you use to draft
the hydraulic gradeline. If a hydraulic grade line elevation in value is not entered, the
Pipes Run Editor uses the default hydraulic grade line elevation in value from the Pipes
settings.
HGL Elev Out This column contains the hydraulic grade line elevation out value, which you use to draft
the hydraulic gradeline. If a hydraulic grade line elevation out value is not entered, the
Pipes Run Editor uses the default hydraulic grade line elevation out value from the Pipes
settings.
