Head-discharge relationships for rectangular flat-crested slit weir / Rosley Jaafar
The rectangular weir is the most commonly used device in channel and laboratory for flow measurement due to its simplicity. The rectangular sharp-crested slit weir has been shown to be good at measuring small (< 0.005 m3/s) flow rates. In this study, the rectangular slit weir concept is extended...

The rectangular weir is the most commonly used device in channel and laboratory for flow measurement due to its simplicity. The rectangular sharp-crested slit weir has been shown to be good at measuring small (< 0.005 m3/s) flow rates. In this study, the rectangular slit weir concept is extended to find the head-discharge relationship of water flows over a contracted rectangular flat-crested slit weir under free flow conditions. The head-discharge relationship is determined experimentally using a nine different weir heights with 10 mm weir width and 4 mm weir crest thickness at small discharges (< 0.00067 m3/s). The experimental data of actual and predicted discharge is verified by using a statistical analysis. A linear regression equation correlating the head-discharge relationship provides an accurate prediction of free flow discharge over the weir to yield results within 2.1% error of actual discharges and have a strong relationship. The presented head-discharge equation can use to estimate the discharge flow of water over rectangular flat-crested slit weir with an appropriate limitation. |
