(5) Water flows along a trapezoidal channel with base width B=1.5 m, side slope 1:1 (horizontal to vertical) and depth D=0.7 m. It is controlled downstream by a sharp crested weir that has a crest height of H=2.4 m above the channel bed and a crest width equal to that of the base width. Calculate the flow rate in the channel (check any assumptions you make).
