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.
Infilt. Inflow
This column contains the infiltration inflow value of the pipe segment.
Lateral Flow #1
This column contains the flow contribution to the pipes upstream node for the first lateral
run. If a valid lateral run name is entered in the Lateral Name #1 column, this value is
automatically calculated.
Lateral Flow #2
This column contains the flow contribution to the pipes upstream node for the second
lateral run. If a valid lateral run name is entered in the Lateral Name #2 column, this value
is automatically calculated.
Lateral Inv. #1
This column contains the invert elevation at the pipes discharge point run for the first
lateral invert. If a valid lateral run name is entered in the Lateral Name #1 column, this
value is automatically calculated.
