You are designing a hydroelectric plant. The turbine has an efficiency of 88% and the generator has an efficiency of 92%. You design the water flow rate to be 110 m3/s. The water elevation drop is 120 m. Disregarding frictional loss in the piping, what do you expect the electric power output to be in MW?

A micro hydro turbine is used to generate hydroelectric power by letting liquid water from a high elevation run through the turbine to a low elevation. The turbine is under a steady state operation condition. The inlet water and outlet water are at elevations of 10 m and 2 m, respectively. The inlet and outlet diameters are 0.3 m and 0.5 m, respectively. The inlet pressure is 2.5 bar and the outlet pressure 1 bar. The inlet and outlet temperatures...

9) Electrical power is to be generated by installing a hydraulic turbine-generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 350 kW, determine the turbine efficiency and the combined turbine-generator efficiency of this plant. Neglect losses in the pipes. (10pts).

A pumped-storage hydroelectric plant generates high value electricity during peak demand times, by allowing water (density 1,000 kg/m3) to run through a pipe from an elevated reservoir through a bank of turbines and then into a lower level reservoir. It then uses low-cost, off-peak electricity to pump the water back up into the upper reservoir The water surface in the very large upper reservoir (A) is 600 m above datum whilst that in the very large lower reservoir (B) is...
