What are water turbines?
Water turbines are used to extract energy from movable water, usually for the production of hydroelectrics. They work by forcing water around the oblique blades that spin the turbines. Water turbines can be mechanically connected to the machine or to the electric generator. Steam turbines use gaseous steam than liquid water.
Water turbine precursor was a water wheel that has been used for thousands of years. The water wheel is oriented vertically and only a small part submerged underwater is submerged under water. This type of wheel is relied on the horizontal momentum of the water in the river to turn. To work, the bike must have ridges or buckets to capture water. The same principle is used in a paddle wheel of a steamboat.
, however, water turbines work in a different way, with blades arranged in an analogous windmill. The fluid flows through a windmill rather than around it. The same design is used for waters, although the shape of the blades is optimized Pro water instead of air.
Water turbine began to be used extensively during the 19th century. Before electricity was available, the factories were mechanically powered. Water turbines were attached to the machines as well as the car engine is connected to its wheels. The engine can continue to rotate while the transmission distributes the wheel power by creating or breaking a mechanical connection. In a similar way, the factory can be powered without electricity.
Recently, water turbines have been used in hydroelectric power plants. These plants usually include a dam with a significant difference in the water level between the sides. The plant extracts gravitational potential energy stored in higher water by forcing it to flow through water turbines; In other words, the water falls from a high level of low levels pushing the water turbine and turns the turbine. The rotary energy is converted into electricity by means of electric GENeror. In 2008, the hydroelectrity represented most of the renewable energy produced worldwide.
steam turbines, on the other hand, use the energy of steam instead of liquid water. They are considerably used in other types of power plants. In fact, the steam turbine is the primary method of converting thermal energy into kinetic energy in large applications. Whether the heat in the power plant comes from burning coal or nuclear cleavage, it is used to cook water and steam production. The high -pressure steam is then diverted to flow through the turbine, causing it to rotate quickly and turn the electric generator.
