In a hydroelectric dam, water falls 27.0m and then spins a turbine to generate electricity.
What is ?U of 1.0 kg of water?
(???)
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 52.0MW of electricity? This is a typical value for a small hydroelectric dam.
