The Pipe Size Library command allows you to store the dimensions of the widely used pipes. There are four pipe sections: box, circular, horizontal ellipse and vertical ellipse. The working structure data file is stored (by default) in the %AppData%\Carlson Software\...\User\PipeSize.dta file and is available across all Carlson Software projects.
From the Network > Sewer Network Libraries menu in the
Hydrology Module, select Pipe Size Library to open the library
dialog. The Section Type list contains four section types. You can
select one pipe shape to display all the pipe sizes of that shape
in the spreadsheet. In the right column of the spreadsheet, the
Available in Design check boxes are listed next to the pipe sizes
indicating that whether the pipe sizes are available in the pipe
size design or not. You may choose to display the Min/Max Cover,
Min/Max Slope, Min/Max Velocity and Cradle Data on the spreadsheet.
These parameters are used in sewer network design and
analysis.
The Custom Properties function defines additional fields for each pipe. Values for these fields can be entered into the Pipe Size Library. Then these fields are available in the Report Sewer Network command.
New button adds a new pipe size, Edit button allows you to modify an existing pipe size, and Delete button removes the highlighted pipe size from the library. Load and SaveAs buttons allow you to load and save the pipe size data.
In the Circular Section dialog, type the value in the Diameter box, and then the full cross-section area is calculated and displayed. You may fill in the Design Constraints and Cradle Info for sewer network analysis and sewer profiles. Click on OK button to commit the pipe size entry.
In the Box Section dialog, type the values in the Height and Width boxes, and then the full cross-section area is calculated and displayed. You may fill in the Design Constraints and Cradle Info for sewer network analysis and sewer profiles. Click on OK button to commit the pipe size entry.
In the Horizontal and Vertical Ellipse Section dialog, type the values in the Rise, Span and Full Area boxes. The Equivalent Diameter is the diameter of a circular section that is equivalent to the ellipse. The Flow Area Factor is the ratio of the calculated full area to the specified full area. A0, A1, A2, A3 and A4 are the five coefficients to the 4th order polynomial equation, which describes the relationship between the wetted perimeter (in) of the ellipse and the depth/rise ratio, as below.
p = A0 + A1 (d/r) + A2 (d/r)2 + A3 (d/r)3 + A4 (d/r)4, where:
p = wetted perimeter (in or mm)
d = water depth in the pipe (ft or m)
r = pipe rise (ft or m)
Default Libraries
There are several default libraries for North Carolina under
Carlson Projects\Settings\NorthCarolina. Use the Load function to
select a library.
