Energy Relation for Closed Conduit Flow
Conservation of energy involves a balance in total energy, expressed as head, between any upstream point of flow and a corresponding downstream point, including head losses caused by friction …
Gutter Flow
Gutters are the sections of roadway that run adjacent to the curb. Their purpose is to collect and convey surface runoff to drainage inlets and in turn to underground storm sewers. The corresponding …
When the flow is Supercritical in an upstream section of a channel and is then forced to become subcritical in a downstream section, a rather abrupt change in depth usually occurs and …
