Hoover Dam on the Colorado River is the highest dam in the United States at 221 m, with an output of 1300 MW. The dam generates electricity with water taken from a depth of 103 m and an average flow rate of 640 m3/s.   Calculate the power in this flow in watts.

Water is pumped through a pipe of diameter 15.0cm from the Colorado River up to Grand Canyon Village on the rim of the canyon. The river is at 564m elevation and the village is at 2 096 in(a) At What minimum pressure must the water be pumped to arrive at the village? b) If 4500 m3 are pumped per day what is the speed of the water in the pipe? (c) What additional pressure is necessary to deliver this flow? Note you may assume the free- fall acceleration and the density of air are constant over the given range of elevations.
