You are tasked to comment on the sizing and potential applications of a proposed hydroelectric power station along a river which supplies 2.3t/s steadily at a velocity of 3.1m/s. The electric power would be generated by installing a turbine-generator unit with an efficiency of 76%. As shown in the sketch, at the dam the total mass flow rate of the river is made of those of the Ahuroa river, the Bluff river (17% of the total flow) and Clyde river (25% of the total flow). After the dam, 6% of the river branches off into Dark river.
