Orifice in storm line with back water pressure
Orifice in storm line with back water pressure
(OP)
Planned to install three orifices along the storm line CBMHs which pases three sub cathcments. Let water pond on the three surfaces to three different elevations.
Used rational formular and hand calculations to control 100yr storm allowable peak flows.
When I sized the last orifice to have required ponding depth and peak flow, it create a back water flow on second orifice. It may reduce the total flow from second orifice.
How can I resolve this problem? Appreciate all your help!
