Explain the energy changes taking place in a hydroelectric dam?
टिप्पणी लिखिए
उत्तर
Energy changes taking place in a hydroelectric dam:
- As the water flows into reservoir from the catchment area, the kinetic energy of flowing water changes to potential energy.
- As the water is released through a control valve, the potential energy of water changes to kinetic energy.
- As the water flowing at a high speed strikes the blades of the turbine, its kinetic energy changes to the rotational kinetic energy of the turbine.
- As the turbine is coupled to the shaft of the generator, the rotational kinetic energy of the turbine changes to the rotational kinetic energy of armature.
- As the coils of armature rotate in the magnetic field, the rotational kinetic energy of armature changes to the electric energy in its coils.
