A weir is used to measure the flowrate in an open channel that is (Bw =) 5 m wide and (Ho =) 2 m deep. The depth of water over the crest of the weir (H) should be no less than 0.5 m when the flowrate (Q) is 1 m3/s and the water level should be at least 30 cm below the top of the channel. Determine the crest length of the weir (B).
