A dam covers an area 2000m long and 1500m wide, with a depth of 40 metres. If the centre of the dam sits 300m above a turbine through which all of the water will be passed, what is the total electrical energy (in TJ) that can be derived if the dam is completely emptied? (Assume no losses. g=9.81 m.s-2 and the density of water is 1000 kg.m-3)
