In this function, the peak design flow is determined according to the Harmon formula:

The defaults are normally read from the ProgramData directory when creating a new data file, unless the SetSharedFolder utility has been run to set a shared network resource. The SetSharedFolder utility is on the installation CD.

If no data set is open and the defaults are changed, the changes are saved in either the ProgramData directory, or in the Shared Folder if it has been set.

If a data set is open, the changes are stored with that data set.

All these settings can be individually changed in the Edit Node or Edit Link functions; or on selected (marked) nodes and links using the Set Parameters function.

Procedure

  1. The number of contributing dwelling units can be input for each manhole. During the design process, the cumulative number of contributing units is determined at each node, and from that the design flow is calculated from the formula described above.

  2. You can adjust the following parameters in the Harmon Parameters.

  1. Specify the unit flow and contributors per unit, and then click OK.
