The height of water in hoover dam is 222 m when lake mead is full. for a nominal flowrate of 1060 m3/s the water comes out the bottom at 13 m/s. what is the power in gw? for this problem, ignore the energy lost through friction. make sure you use the correct sign for the change in height.
in reality, the dam’s thermal efficiency is about 90 %, which means about 10% of the power is lost to friction. in all types of power generation plants, there are additional energy losses that occur later in the electric generator and in the power lines
