A '''turbine''' is a machine for generating rotary mechanical [[power]] from the [[energy]] of a stream of fluid (such as [[water]], [[steam]], or hot [[gas]]). Turbines convert the [[kinetic energy]] of fluids to mechanical energy through the principles of impulse and reaction, or a mixture of the two. | A '''turbine''' is a machine for generating rotary mechanical [[power]] from the [[energy]] of a stream of fluid (such as [[water]], [[steam]], or hot [[gas]]).
