Reaction turbines require about twice as many stages as impulse-staged turbines for the same change in steam enthalpy. The cost and size of the turbines, however, are about the same because blading for pressure staging must withstand greater forces and must therefore be more rigidly constructed.

The steam turbine is a device for obtaining mechanical work from the energy stored in steam. There are two main types of turbine, the 'impulse' and the 'reaction'. The names refer to the type of force which acts on the blades to turn the turbine wheel. An impulse turbine is a turbine that is driven by high velocity jets of water or steam from a nozzle directed on to vanes or buckets attached to a wheel. The resulting impulse (as described by Newton's second law of motion) spins the turbine and removes kinetic energy from the fluid flow. Each side of the turbine has a different pressure due to the hot expanded steam on one side and colder denser air on the other, and so the steam runs through the turbine to the colder side, turning the turbine rotor. Rotors can be "impulse," which means the force of the steam entering turns the rotor, or "reaction," where the rotor is turned by ...
