A tidal power plant of the simple single basin type shown in Figure Q5(c)(i), has a basin area of \( 30 \times 10^{6} \mathrm{~m}^{2} \). The tide has a range of \( 18 \mathrm{~m} \). The turbine, however, stops operating when the head on it falls below \( 5 \mathrm{~m} \). Calculate the energy generated in one filling (or emptying) process, in kilowatt hours if the turbine generator efficiency is \( 0.73 \). The total time it takes the cycle to repeat itself is 6 hours, \( 12.5 \mathrm{~min} \) as \( 9.80 \mathrm{~m} / \mathrm{s}^{2} \), and assuming an average sea water density of \( 1025 \mathrm{~kg} / \mathrm{m}^{3} \).
