A hydraulic power system, as shown in the picture, has an elevation difference between the reservoir water surface and the downstream water pond surface of H( 7 m). A discharge of 0.8 m3/s flows through the penstock and spins a hydraulic turbine, which in turn drives a generator to produce electric power. Estimate the electric power generated if the head loss through the entrance, penstock and exit is 1 m, L and the efficiency of the turbine and generator are...

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...

A Pelton wheel with an efficiency of 85% is used to produce hydroelectric power from flow of water behind a dam with an elevation head of 420 m. The average radius of the wheel and its angular velocity are 2.0 m and 220 rpm, respectively. This turbine works at its optimum rotation rate (which produces maximum power). The turning angle of the buckets is ? = 165° and nozzle diameter is given as 8.00 cm. a. Calculate volumetric flow rate...

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).

3. In a small hydroelectric power station, the turbine uses the energy of the water in the reservoir behind the dam to produce 12000 horsepower. The circular channels before and after the turbine have a diameter of 90 inches. If the head loss across the dam can be calculated from hloss=cV²/2g where c=8 and V is the water velocity in the circular channel, calculate the volumetric flow rate, Q, through the system and the corresponding head loss for h=400 ft...
