A hydroelectric power plant is situated at the base of a dam. Water exits the power plant 120 m below the top of the reservoir at a speed of about 4 m/s (at atmospheric pressure). The volume flow rate of water through the power plant is 1000 m3/s. The plant operates with an energy efficiency of 80% and produces a peak voltage of 10 kV. Estimate the maximum possible peak current and the maximum possible power output that the power plant can supply.
