Electric power is to be generated by installing a hydraulic turbine-generator at a site 138 m below the free surface of a large water reservoir that can supply water at a rate of 2400 kg/s steadily. Determine the power generation potential. Assume that the elevation of the reservoir remains constant and the mechanical energy of water at the turbine exit is negligible. (Round the final answer to two decimal places.)

The power generation potential is 3245.76kW

Explanation:

Power = mass flow rate * acceleration due to gravity * height = 2400kg/s * 9.8m/s^2 * 138m = 3245760W = 3245760/1000 = 3245.76kW (to 2 decimal places)
