Impulse turbines are a type of water turbine that convert the kinetic energy of flowing water into mechanical energy. They operate by directing a high-speed jet of water onto the turbine blades, causing them to spin. This design is particularly effective in high-head applications, where water falls from a significant height. The most common example of an impulse turbine is the Pelton wheel. In this system, water is released from a reservoir and directed through nozzles, creating jets that strike the turbine's cups. The energy from the water jet is transferred to the turbine, generating electricity in hydroelectric power plants.
