what is the working principle of turbine?

Answer 1

To efficiently convert the kinetic energy of a fluid, into torque (and therfore angular kinetic energy).

The fluid is generally either liquid water under pressure, or steam under pressure, or in the case of an airplane or gas turbine engine, air and combustion gasses.

The fluid impinges on the blades of the turbine, imparting energy to rotate the blades.

Answer 2

Principle Of Turbine

Answer 3

The working principle of turbine is (rotation = energy or energy = rotation, it works both ways). The rotation of the of the object via blades propelled or repelled, either producing energy i.e. wind turbines or requiring energy i.e. Jet engines. So rotation = energy either plus or minus.
