A hydropower plant utilizes eight Francis turbines. The change in head across the power plant is 250 m, and the flow through each turbine unit is 12 m3 /s. The estimated efficiency of each turbine unit is 95%, and the efficiency of the generator and supporting power delivery systems is 91%. Estimate the power-generating capacity of the hydropower facility. Assume water at 20◦C.
