3. One method of producing energy is to use a tapered channel (TAPCHAN), which diverts sea water into a reservoir as shown. As a wave approaches the shore through the closed tapered channel at A, its height will begin to increase until it begins to spill over the sides and into the reservoir. The water in the reservoir then passes through the turbine in the building at C to generate power and is returned to the sea at D. If the speed of the water at A is V = 2.5 m/s, and the water depth is ha = 3 m, determine the minimum height h at the back B of the channel to prevent the water from entering the reservoir. V = 2.5 m/s
