Perhaps the most famous hydroelectric plant in the United States is Hoover Dam, placed on the Colorado River at the Arizona/Nevada border. This facility can generate about 2 GW of power (a lot). The water in this dam falls a distance of 500 ft to get to the turbines. Required:
At this power capacity, what is the volume of water passing through the system each second?
