A hydro-electric station is operated with a mean head (h) of 30 m and the water is supplied from a lake which its dimentions are 250 square km (area) and 125 cm (depth), 70% of the water in this lake can be utilized yearly to obtain the average load. If the expected load factor for the station is 80%. Calculate the power in kw for which the station should be designed (max. load). Assume that the mechanical efficiency of the turbine is 90% and the efficiency of the generato: is 95%
