(1) Hydraulic turbines convert the potential energy of water into shaft work, which, in turn, rotates the electric generator coupled to it in producing electric power. Pelton turbine named after Lester Allen Pelton of the USA, an impulse turbine used for high head and low discharge. In an impulse turbine all the available head of water is converted into kinetic energy in a nozzle. The water shoots out of the nozzle in a free jet into a bucket which revolves...

The state of Iowa is among the top three states in U.S. in wind power generation. In 2016, over 20 billion kWh of electrical energy in Iowa was generated by wind power. Assuming that wind speed at the altitude of wind turbine is in average of 6 m/s, the efficiency of converting wind energy to the electricity is 80 %, and all wind turbines work constantly throughout the year. We can further assume that the air in Iowa has an...

Water under a head of 300 m is available for a hydel-plant situated at a distance of 2.35 km from the source. The frictional losses of energy for transporting water is equivalent to 26 m. A number of Pelton wheels are to be installed generating a total output of 18 MW. Determine the number of units to be installed, diameter of Pelton wheel and the jet diameter when the following data are available: Wheel speed 650 rpm.; ratio of bucket...
