Newton’s third law of motion (actions and reactions are equal but opposite in direction) describes the working of the reaction turbine (RT). Witrynaturbines. Most steam turbines use a mixture of the reaction and impulse designs: each stage behaves as either one or the other, but the overall turbine uses both. Typically, higher pressure sections are impulse type and lower pressure stages are reaction type. Impulse turbines An impulse turbine has fixed nozzles that orient the diamondhead chapel
