WebAug 29, 2024 · A reaction turbine’s torque is generated by reacting to fluid pressure or weight. According to Newton’s third law of motion, the operation of reaction turbines can be explained (action and reaction are equal and opposite). Reaction turbine nozzles are attached to the rotor, unlike impulse turbines. WebA Francis turbine is a type of reaction turbine used most frequently in medium- or large-scale hydroelectric plants. These turbines can be used for heads as low as 2 meters and as high as 300 meters. Additionally, these turbines are beneficial as they work equally well when positioned horizontally as they do when they are oriented vertically.
