Hydroelectric power, that is the mating of centuries-old hydraulic power machines, such as waterwheels and turbines, with electric generators was a foregone conclusion once generators became commercially available. Although the first generating station was steam-powered, it must be remembered that steam engines were used at that time primarily as a substitute for water power in locations were water power was not available.Lester Allen Pelton is commonly mentioned as the inventor of hydroelectric power. This is not true. Pelton invented a type of hydraulic turbine that used a free-jet impulse system to turn a wheel; he patented his Pelton turbine in 1880. Pelton wheels were widely used to provide mechanical power for mining operations in the mountainous country of the western US. In 1887, miners connected a generator to a Pelton wheel and began generating electricity, but Pelton himself had nothing to do with this development.Five years earlier, in Appleton, Wisconsin, the Vulcan Street Plant went into operation on September 30, 1882. It generated electricity using the power of water from the Fox River already impounded by a dam at an existing paper mill. The plant was the brainchild of two men: H. J. Rogers, president of the Appleton Paper and Pulp Co. and the Appleton Gas Light Co., and H. E. Jacobs, who was a licensing agent for the Western Edison Light Co. of Chicago. The two men were friends, and it is believed that they developed the idea while on a fishing trip together. The Vulcan Street Plant is considered to be the first hydroelectric generating station in the world.Lester Allan Pelton was an American inventor who created an efficient form of impulse water turbine in 1878 in the goldfields.In 1887 a miner attached Pelton's wheel to a dynamo and produced the first hydroelectric power in the Sierra Nevada Mountains.Just to let everyone know hydroelectric power wasnt created. He just discovered it and found ways to use it.Nikola Tesla developed the first working system at Niagara Falls. The system is still over on the Canadian side with a statue of the man. Quite a work of engineering excellence.
generally for a condensing turbine the quantity for generating one MW electricity the steam quantity remains 8.5 t/h. it will depend on the design of Turbine in Our project it is 5.5 t/MW
Motor size depends upon number of factore. 1- flow of pupm 2- required head 3- efficiency of pupm used 4- efficiency of electric motor used The formula is H.P required= Q.H\ 3960. Pump efficiency.

This Tesla CD Turbine is based on the Tesla turbine, which was invented by Nikola Tesla in the early 1900's. Tesla's pumps and motors were unique in that they only used discs, and took advantage of the boundary layer effect. His smallest designs were over 100 horsepower. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine, cohesion-type turbine, and Prandtl layer turbine (after Ludwig Prandtl). One of Tesla's desire for implementation of this turbine was for geothermal power, which was described in "Our Future Motive Power". Tesla wrote 'This turbine is an efficient self-starting prime mover which may be operated as a steam or mixed fluid turbine at will, without changes in construction and is on this account very convenient. Minor departures from the turbine, as may be dictated by the circumstances in each case, will obviously suggest themselves but if it is carried out on these general lines it will be found highly profitable to the owners of the steam plant while permitting the use of their old installation. However, the best economic results in the development of power from steam by the Tesla turbine will be obtained in plants especially adapted for the purpose.
A wind turbine can use up to 40kw/h of energy at once. When for example the turbine is yawing into the wind (turning the head of the turbine into the wind for the blades to face the incoming wind). 4 high power motors and gears are used to do this. When at the same time the hydraulic system is turned on to control the blades to position themselves in the wind, and the motors for the cooling are enabled, the windturbine can require a lot of wind. However usually this is generated by the turbine itself. So this is not really relevant as the output is much higher then the usage.
pelton wheel is used for high heat because it has less loses....n more efficiency... pelton wheel is used for high heat because it has less loses....n more efficiency... eeeeeee.com parama boka dheni chudaka
In a water turbine.
pelton turbine is used for high head low flow but the turgo turbine is used for low head high flow, in pelton turbine number of jet can increased but in turgo it can't be done, in pelton the water hits the bucket once at a time but in tugo it hits more than one
pelton turbines are suited to high head,low flow application but kaplan turbine are used for low head and a large amount of discharge needed. kaplan turbines are expensive to design,manufacture and install as compared to pelton turbine but operate for decades.
Lester Allen Pelton invented a type of free-jet water turbine called the Pelton Wheel. Before him, people used watermills to turn wheat into flour.
The Pelton wheel in the turbine is most likely to break. This is because the part is used to protect the turbine during winter freeze-up and spring break-up,
The Kaplan turbine is a newer, more revolutionary version of the Francis turbine, which came before it. The draft tube is used so that the turbine does not need to be where the water flow is lowest.
Due to the nature of turbines,there are several parts that can break. You are most likely to have a belt break. The Pelton wheel in the turbine is most likely to break. This is because the part is used to protect the turbine during winter freeze-up and spring break-up,
Pelton wheel could be used to lift water from a lower source (lake or something) to pour into a high place. Another use, it could be used to dig into the earth, the wheel have the shape of a milling cutter, it can open channels in the ground or something. It could also be used to measure the speed of a fluid, if connected to a dynamo meter, the speed of flow could be read via voltage. These are some applications. BY: FAISAL RAFIQUE
Type your answer here... turbines are mainly used to convert hydraulic energy into mechanical energy.kaplan ,francis and pelton are the turbines.
1 Pelton Turbine 2 Kaplan Turbine 3 Francis Turbine 4 Propeller Turbine 5 Tubular Turbine
a turbine would be used instead of a water wheel because a turbine does not use as much energy and it uses the wind to generate it.
