Entering Additional Data to Link Elements

In document SewerCAD V8i Users Guide (Page 190-195)

There are several dialog boxes that are available from the Property Editors that let you enter additional data for link elements.

• “Adding a Minor Loss Collection to a Pressure Pipe” on page 6-171 • “Defining the Geometry of a Link Element” on page 6-172

• “Defining the Cross-Sectional Shape of a Link Element” on page 6-174 Layout tool

Adding a Minor Loss Collection to a Pressure Pipe

Pressure pipes can have an unlimited number of minor loss elements associated with them. SewerCAD V8i provides an easy-to-use table for editing these minor loss collections in the Minor Loss Collection dialog box.

Note: For more information on minor losses, see “Minor Losses” on

page 13-660.

To add a minor loss collection to a pressure pipe:

1. Click a pressure pipe in your model to display the Property Editor, or right-click a pressure pipe and select Properties from the shortcut menu.

2. In the Physical: Minor Losses section of the Property Editor, click the Ellipses (...) button next to the Minor Loss Coefficient field.

3. In the Minor Loss Collection dialog box, each row in the table represents a single minor loss type and its associated headloss coefficient. For each row in the table, perform the following steps:

a. Type the number of minor losses of the same type to be added to the

composite minor loss for the pipe in the Quantity column, then press the Tab key to move to the Minor Loss column.

b. Click the Ellipses (...) button in the Minor Loss column to display the Minor Loss Libraries in the Engineering Libraries.

c. Click the plus signs to expand the Minor Loss Libraries, then select the desired minor loss type and click the Select button. The minor loss type and its associated headloss coefficient appears in the table in the Minor Loss Collection dialog box. Note that the Headloss Coefficient column in the table is not editable.

Note: You can edit the values of a minor loss type in the Engineering Libraries in the Editor pane.

4. When you are finished adding minor losses to the table, click Close. The

composite minor loss coefficient for the minor loss collection appears in the Prop- erty Editor.

5. Perform the following optional steps:

To delete a row from the table, select the row label then click Delete.To view a report on the minor loss collection, click Report.

6. You can override the headloss coefficient for the minor loss collection by typing a custom value in the Minor Loss Coefficient field of the Property Editor.

Minor Loss Collection Dialog Box

The Minor Loss Collection dialog box contains buttons and a minor loss table. The dialog box contains the following controls:

The table contains the following columns:

Diversion Rating Curve Dialog Box

This dialog allows you to define the rating curve using Upstream Flow vs. Diverted Flow points. The rating curve determines the flow into the associated conduit. At each upstream flow point, you define how much of the flow is diverted.

Defining the Geometry of a Link Element

You define the geometry of a link element by entering the location and angle of bends for the selected link element. You enter X vs. Y points that plot the shape of the polyline that represents the element in the Polyline Vertices dialog box .

New This button creates a new row in the table.

Delete This button deletes the currently highlighted row from the table.

Report Opens a print preview window containing a report that details the input data for this dialog box.

Column Description

Quantity The number of minor losses of the same type to be added to the composite minor loss for the pipe. Minor Loss The type of minor loss element. Clicking the

Ellipses button next to this field displays the Minor Loss Engineering Libraries, where you select an existing minor loss type to be included in your minor loss collection.

Headloss Coefficient The headloss coefficient for a single minor loss element of the specified type.

To define the geometry of a link element:

1. Click a link element in your model to display the Property Editor, or right-click a link element and select Properties from the shortcut menu.

2. In the Geometry section of the Property Editor, click the Ellipses (...) button next to the Geometry field.

3. In the Polyline Vertices dialog box, click the New button to add a new row to the table.

4. Type values for X and Y points for each row in the table. 5. To remove rows from the table, click the Delete button. 6. Click OK.

Polyline Vertices Dialog Box

This dialog box contains the X vs. Y table that allows you to define any number of points that plot the shape of the polyline representing the selected link element. The dialog box contains the following controls:

Irregular Channel Editor Dialog Box

The Irregular Channel editor dialog box contains buttons, a Station vs Depth table, and a diagram window that plots the station-elevation curve defined by the points in the table. The dialog box contains the following controls:

New This button creates a new row in the table.

Delete This button deletes the currently highlighted row from the table.

The table contains the following columns:

Defining the Cross-Sectional Shape of a Link Element

You define the cross-sectional shapes of link elements in their respective Property Editor as follows:

• Define the cross-sectional shape of a conduit section by entering data in the Phys- ical section of the element’s Property Editor.

• Define the circular shape of a pressure pipe by entering data in the Physical section of the element’s Property Editor.

You access the curve dialog boxes in the selected link element’s Property Editor. New This button creates a new row in the Station

vs Depth table.

Delete This button deletes the currently highlighted row from the Station vs Depth table.

Report Opens a print preview window containing a report that details the input data for this dialog box.

Help Opens the online help.

Column Description

Station This field allows you to define the cross-sectional distance at the current curve point. You can enter these in any order that defines the channel (e.g., from left-to-right, from right-to-left, with an upstream or downstream perspective).

Depth This field allows you to define the depth at the corresponding station for an irregular channel. The depth value is relative to the invert of the channel (a Depth value of 1.0 ft will be 1.0 ft above the invert, a Depth value of -1.0 ft will be 1.0 ft below the invert). This value can be a negative number.
