A hydroelectric power plant uses spinning turbines to transform the kinetic energy of moving water into electric energy with 80 % efficiency. That is, 80 % of the kinetic energy becomes electric energy. A small hydroelectric plant at the base of a dam generates 40 MW of electric power when the falling water has a speed of 18 m/s.
What is the water flow rate −kilograms of water per second − through the turbines? Express your answer with the appropriate units.
