The flow rate of water flowing in a 3 m wide channel is to be measured with a sharp crested triangular weir, where the apex is 0.5 m above the channel bottom with a notch angle of 60°. If the flow depth up stream is 1.5 m. determine the volumetric flow rate of water through the channel. Take C, as 0.6.
