A hydroelectric station has a mean head of 30m and receives inflow from a catchment area of 300km2 having an average rainfall of 200cm per year. the rainfall occurs during the monsoon period of 90 days in a year. the storage capacity of the station is limited to half the total inflow. if 70% rainfall reaches the reservoir, determine the minimum capacity of the station. assume that no heads lost in pipes, e.c.t. and the efficiencies of the turbine and generator are 85% and 95% respectively. determine also the total energy produced and the plant use factor.
