These types are reaction turbines and impulse turbines. Two types of turbines are generally found in these facilities, and the choice of which to use depends on the characteristics of the hydroelectric facility. These factors include hydraulic head, hydroelectric discharge, and the cost. There are many factors that must be investigated to determine which turbine should be used. Each type of turbine is created to provide maximum output for the situation it is used in (examples of different types of hydropower turbines include francis turbines, kaplan turbines and pelton turbines). There are a variety of different types of turbines that are best used in different situations. This rotational motion is then transferred to a generator where electricity is generated. Water is then passed through the turbine over the blades, causing the inner shaft to rotate. A row of blades is fitted to some rotating shaft or plate. The construction of hydroelectric turbines is similar for different types of hydroelectric plants (see run-of-the-river hydroelectricity and impoundment for more information). These turbines are essential in the area of hydropower - the process of obtaining power from water. The water, which has kinetic and potential energy, is allowed to fall on a turbine which spins a shaft connected to a generator, thus generating electricity. In a hydroelectric facility, water is held behind a dam and is released through a penstock. Turbines are extremely important because of the fact that nearly all electricity is produced by turning mechanical energy from a turbine into electrical energy via a generator. Turbines are used in wind power, hydropower, in heat engines, and for propulsion. Turbines are used in many different areas, and each type of turbine has a slightly different construction to perform its job properly. Fluid flowing through a turbine loses kinetic energy and exits the turbine with less energy than it started with. These blades spin while the fluid flows through, capturing some of the energy as rotational motion. A simple turbine is composed of a series of blades - currently steel is one of the most common materials used - and allows the fluid to enter the turbine, pushing the blades. Turbines are machines (specifically turbomachines) because turbines transmit and modify energy. Turbines are generally used in electrical generation, engines, and propulsion systems. Ī turbine is a device that harnesses the kinetic energy of some fluid - such as water, steam, air, or combustion gases - and turns this into the rotational motion of the device itself. Turbines can be fairly large, the steam turbine above is put into scale with a person.
