Water from a large tank is used to generate electricity by installing a hydraulic turbine- generator at 100 m down from the water surface as shown in Figure QS. The water is supplied to the turbine at a rate of 2000 kg's. If the mechanical power input of the turbine is 1800 kW and the generator efficiency is 80%, determine the percentage reduction of efficiency between generator alone and combination of turbine-generator Consider the water density as 1000 kg/m (7...

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...

9. The absolute pressure in water at a depth of 5 m is 145 kPa. What is the absolute pressure in a liquid whose specific gravity is 1.34 at the same depth? Hint: Determine the atmaspheric pressure first 10. Water is pumped from a lake to a storage tank 30 m above at a rate of 55 L/s, while consuming 22.6 kW of electrie power to run the motor. Detemine the overall efficiency of the motor-pump unit. .A hydraulic power...

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...

a) The following figure shows a water dam built for a hydroelectric power project running constantly round the year. During a dry season, it acts as water reservoir of constant height 80 m. Meanwhile rainy season, water flow of 3 m/s is added to the system. (Water density 10x10 kg/m' and volume flow, V = 45x10 m/s respectively and the gravitational acceleration is about 9.8 kg/m for both seasons).
