WebJul 22, 2024 · If it is a parallel orifice but elevated in relation to the bottom of the pond, you may want to consider modeling this as a riser. A riser will use the weir equation if the water elevation is right at the height of the riser, but the orifice equation if it is above the top of the riser. Regards, Scott WebApr 12, 2024 · In this research, the flow and scour patterns downstream of type-A rectangular piano key weirs (PKWs) were studied experimentally and numerically. Variations of the bed topography downstream of the PKW with different lateral crest shapes, i.e., a standard crest and a crest with an indentation in various geometries, including triangular, …

This procedure of practice of the thin plate weirs of standard geometric shape has increased the discharging coefficient.This paper is concerned with the experimentation, analysis and development of discharge–head-inclination model to measure flow over inclined triangular weir with a new approach. WebThis work investigates a hydrodynamic problem involving the Fe3O4-Water nanofluid. The novelty of this investigation lies in the fact that the nanofluid free convection is evaluated within a specific rectangular enclosure having a finned absorber plate as the top wall, heated by solar energy. The fins below the absorber plate permit to enhance heat transfer …
