Integrated Concepts
Hydroelectric generators (see Figure \(20.43\)) at Hoover Dam produce a maximum current of \(8.00 \times 10^{3} \mathrm{~A}\) at \(250 kV\).
(a) What is the power output?
(b) The water that powers the generators enters and leaves the system at low speed (thus its kinetic energy does not change) but loses \(160 m\) in altitude. How many cubic meters per second are needed, assuming \(85.0 \%\) efficiency?
