Numerical Analysis of Flow Behavior in a Rectangular Channel …

WebThe flow rate measurement in a rectangular weir is based on the Bernoulli Equation principles and can be expressed as: q = 2/3 cd b (2 g)1/2 h3/2 (1) where. q = flow rate (m3/s) h = elevation head on the weir (m) b = width of the weir (m) g = 9.81 (m/s2) - gravity. cd = discharge constant for the weir - must be determined. WebThe calculated over flow parameters are compared against 2D numerical data as well as experimental studies which are showed that: The higher inclined-weir discharging index associated with angle will help to improve discharge coefficient.
