Explain the function of a water turbine in hydro-electric power plant. (5 marks)craft1 electrical June/July 2020

A water turbine is a mechanical device that converts the kinetic energy of flowing water into rotational mechanical energy, which can then be used to generate electricity. In a hydroelectric power plant, the water turbine is a key component that is used to generate electricity from the movement of water.

The water turbine works by channeling water through a system of pipes and channels to a turbine runner, which is a rotating shaft with blades or vanes attached to it. As the water flows over the blades of the runner, it causes the runner to rotate, generating mechanical energy. This mechanical energy is then transmitted through a series of gears and shafts to a generator, which converts it into electricity.
