Energy, Power, and Water Consumption for Hoover Dam When Lake Mead is nearly full, the water at Hoover Dam effectively falls about 191.0 m before encountering the hydroelectric turbines (a more accurate description would be to say that the water is "squirted" through the turbines by the water pressure at the bottom of the lake, but the "squirting" speed is the same as the speed after a free fall of 191.0 m ). After passing through the turbines, the water speed is almost zero. Assume the efficiency of the turbines for generating electric power is 92.9 percent . For this question, use only energy considerations without resorting to a free-body diagram of the water in contact with the blades of the generator turbines. The generators convert mechanical energy to electrical energy with an efficiency of 92.9 percent , meaning only 7.1 percent of the converted mechanical energy is lost to thermal energy. A) Suppose the water level is 93.0 m less than the level listed above. In order to have the same power output as you have calculated in the previous part, what will be the necessary rate of water flow
