hi,
during the design of sewerage network. the following comments appear,
"One or more conduits are operating under pressure at this time step." Hydraulic Results
please clarify why it happen.
what it mean
what is the solution.
Hello Ahmed,
This message means that your conduits HGL is above the top elevation. Generally in a sewerage network you have flow under gravity in conduits. If your conduits carrying capacity is exceeded i.e., it carries more flow than its full capacity it will overflow and the flow will be pressurized flow (like water supply). See this article which explains more about this;
Notifications about conduits operating under pressure or being in the Preissmann slot
Hope this helps.
