WebThis paper is concerned with the development of discharge–head-inclination model to measure flow over inclined Rectangular weir. The considerable increase in the discharging capacity of the weir, with increase in inclination along the vertical plane of weir is ascertained. A new index called inclined-weir-discharging index is defined which is a 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.
