A hydroelectric dam has a penstock that discharges 10^5 kg/s of water. The head of the dam is 80m. a. compute the volume of the discharged water per second (flow rate). b. compute the power of the water entering the turbine. c. Assume that the hydro efficiency is 0.95, the turbine efficiency is 0.9 and the generator efficiency is 92%, estimate the generated electrical power.
