How do the turbine rotates so rapidly when steam is used to rotate it ?

Expert Answer
A turbine rotates at much greater speed (nearly 1800-3600 rpm, which is 100-200 times faster than the wind turbine or water turbine) because it is powered by the energy in hot, gaseous steam which is at incredibly high pressures. This steam expands and cools as it flows past a steam turbine's blades, giving up as much as possible of the energy it originally contained to the turbine blades. Furthermoe, the initial energy that is contained in the water or wind used to rotate the turbine blades is just kinetic energy which is much smaller than the energy contained in the high pressured steam and hence, it results in higher rotational speeds of the turbines.
