In a hydroelectric dam, water falls 32.0 m and then spins a turbine to generate electricity.

Suppose the dam is 80% efficient at converting the water's potential energy to electrical energy. How many kilograms of water must pass through the turbines each second to generate 45.0 MW of electricity? This is a typical value for a small hydroelectric dam.
