The following illustration shows circular pipe values:
Circular pipe values
3
In the Flowrate box, type a flow rate for the pipe (unless you are solving for the
flowrate).
4
In the Length box, type a length for the pipe (unless you are solving for the
length).
You can also click Select to specify the length by selecting an object or points
on the drawing. For more information, see Specifying a Length in this
chapter.
5
In the Headloss box, type a value to account for headloss (unless you are solving
for the headloss).
You can also click Select to specify the headloss value by selecting an object or
points on the drawing. For more information, see Specifying a Headloss Value
in this chapter.
6
In the Coefficient box, type a coefficient value for the selected pipe (unless you
are solving for the coefficient).
You can also click Select to display the Hazen-Williams Roughness Coefficients
dialog box and select a coefficient. This dialog box describes the pipe and the
coefficient value of the pipe. For more information, see Specifying a Hazen
Williams Roughness Coefficient in this chapter.
7
In the Diameter box, type a value for the diameter of the pipe (unless you are
solving for the diameter).
You can also click Select, and pick a diameter form the Pipe Selections dialog
box. For more information, see Specifying a Pipe Diameter in this chapter.
The box in the top-right area of the dialog box displays a graphic of the
currently defined pipe. Based on the values that you entered, information about
the pipe is calculated and displayed at the bottom left of the dialog box. This
information is for display only and cannot be edited.
NOTE
If the data you entered has an error, the pipe graphic image does not
display. Check for an error message at the bottom of the dialog box.
