Investigation Of Water Flow Over Contracted Rectangular Flat-Crested Slit Weir In Open Channel
Empang limpah adalah struktur hidraulik yang tertua dan mudah pembinaannya telah digunakan ke atas saluran terbuka sejak dahulu oleh para jurutera untuk tujuan pengukuran aliran, lesapan tenaga, lencongan aliran, pengaturan kedalaman aliran, saluran banjir dan lain-lain lagi. Terdapat banyak persama...

Empang limpah adalah struktur hidraulik yang tertua dan mudah pembinaannya telah digunakan ke atas saluran terbuka sejak dahulu oleh para jurutera untuk tujuan pengukuran aliran, lesapan tenaga, lencongan aliran, pengaturan kedalaman aliran, saluran banjir dan lain-lain lagi. Terdapat banyak persamaan kadar alir untuk empang limpah bersegiempat tepat puncak tajam pada paras tinggi empang limpah, turus empang limpah dan kadar alir air yang berbagai saiz tetapi sebaliknya bagi empang limpah bersegiempat tepat terkecut lekah puncak rata. Dalam kajian ini, konsep empang limpah lekah diperluaskan ke atas empang limpah bersegiempat tepat terkecut lekah puncak rata yang diuji untuk mengukur kadar alir yang rendah pada paras ketinggian empang limpah yang berlainan.
Weirs are among the oldest and simplest hydraulic structures that have been used for many years by hydraulic engineers for flow measurement, energy dissipation, flow diversion, regulation of flow depth, flood passage and other means in open channels. A number of discharge equations are available for rectangular sharp-crested weirs at various weir heights, weir heads and discharge flows of water but such equations are not available for contracted rectangular flat-crested slit weirs. In this study, the slit weir concept is extended for contracted rectangular flat surface of weir crest to measure the discharges of small flow rates at different weir heights. |
