Question

Could someone help me with this question please as I am kinda lost as in how to do these type of questions

a) Draw a schematic that shows how to harvest tidal energy by a barrage. 8 marks] b) The surface area of the basin is A, the tidal range is R, the density of water is p. What is the maximum power that can be extracted from the tidal range? [5 marks] c) in b) above, turbines with efficiency η are used to produce power. If the basin water level falls at a constant rate, derive an expression for the power output of the turbines in terms of the rate of fall of the water level. 7 marks nlike d) n c) above, the density of the water is 1000 kg/m3, the efficiency of the turbines is 0.90, the tidal range is 2.5 m, the surface area of the basin is 2 km2, the basin water level falls at a rate of 1 meter per hour. Calculate the power output of the turbines. [5 marks

please explain each step
