Question

Please show work. Answer should be 27 MW.

Calculate the power in megawatts available from a tidal power schem incoming tide fills up a catchment area enclosed this water is allowed to fall through openings at the bottom of one of the wa turbines. The square catchment area has 1.2-km sides, and the tide rises by 3.7 m 1-9. e where the by concrete walls, and then at low tide ssume that the process of emptying takes 1.0 h, and that all the energy of the water is converted to energy of the turbines. Hint: when using the expression mgh for gravitational potential energy, remember that h represents the height of the centre of mass.
