Problem. 2 (25%) The flowrate in a water channel is sometimes determined by use of a Venturi flume, as shown in P.2. This device consists of a bump on the bottom of. the channel. If the water surface dips a distance of 0.07 meter for the conditions shown in P.2, what is the flowrate per width of the channel? Assume the velocity is uniform and viscous effects are negligible.
