The One river Hydroelectric Project generated power for BPA along the Two River from the early 1800s until 1900, when it was decommissioned due to environmental issues. The maximum flow rate through the system was 25 m3/s, and the hydraulic head was 98 m. The system used four turbines, each supplied by a 370-m long, 2.7-m diameter penstock. For the sake of analysis, assume the turbine efficiency was 85%. Treat the penstock as concrete with roughness ? = 3 mm, and consider a minor loss coefficient of KL = 18.5. Based on the given flow rate and hydraulic head, what is the maximum possible power that could have been generated? Including the penstock losses and the turbine efficiency, what is a more realistic estimate of the power production?
