Q3: A hydro-electric power station has a reservoir of area 2.5 km²and capacity 5.5 x 10°m³. The effective head of water is 100 meters. The penstock, turbine and generation efficiencies are respectively 90%, 85% and 80%. (1) Calculate the total electrical energy that can be generated from the power station. (2) If a load of 20,000 kW has been supplied for 4 hours, find the fall in reservoir level.
