4 Under Calculate, do one of the following to control the sizing for each pipe run
created:
n
Select the Automatic Pipe Resizing check box to resize the pipes each time
calculations are performed.
n
Clear the Automatic Pipe Resizing check box to keep the size of the pipes the
same. You can manually enter a pipe diameter for each pipe separately.
5 In the Design Settings section, use the Formula list to select one of three
formula options: Manning, Hazen-Williams, and Darcy-Weisbach.
6 In the Design Point (% Full) text box, type a design point value or use the slide
box to adjust the value.
7 In the Pipe Length Calculation Settings section, use the Length type list to select
one of four pipe structure-to-structure length options: Top, Center, Bottom, and
Maximum.
8 In the Hydraulic/Energy Grade Lines section, select the HGL/EGL Calculations
check box to calculate hydraulic and energy grade line elevations
simultaneously with all other pipe run calculations.
NOTE
In the Pipes HGL calculations, all of the junction loss calculations are based
on the velocity calculated, assuming all pipes are flowing full.
9 In the Peak Factor Adjustment section, type the Peak Factor Adjustment value in
the Peak Factor text box.
10 Click Range Set to display the Range Check Settings dialog box.
