The water in a large lake is to be used to generate electricity by the installation of a hydraulic turbine generator at a location where the depth of the water is 50 m. Water is to be supplied at a rate of 5000 kg/s. If the electric power generated is measured to be 1862 kW and the generator efficiency is 95 percent, determine (a) the overall efficiency of the turbine-generator, (b) the mechanical efficiency of the turbine, and (c) the...

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 small town decides to use its water tower to generate emergency power. The water tank holds approximately 50,000 gallons of water, and its top surface is maintained at an elevation, Az, of 33 m above the ground. The town typically needs 250 kW of power. They have an available, 92%-efficient generator, which operates at 60 Hz. They also have an interconnected gearbox with a 5:1 ratio, which can permit lower turbine rotational speeds. a. What type of turbine should...

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...
