A turbine is a machine that converts energy from a fluid, such as air or water, into mechanical energy. This process typically involves the fluid moving through blades attached to a rotor, causing it to spin. Turbines are commonly used in various applications, including electricity generation in power plants and propulsion in aircraft. There are different types of turbines, such as steam turbines, gas turbines, and wind turbines. Each type is designed to harness energy from specific sources. For example, wind turbines capture energy from the wind, while steam turbines use steam produced from boiling water to generate power.
