A hydraulic turbine is a power machine that converts the energy of a water stream into a rotating mechanical energy. It is a turbomachinery in fluid machinery. As early as around 100 BC, China emerged as the prototype of the turbine, the water wheel, used to pump and drive food processing equipment. Most modern hydro turbines are installed in hydropower stations to drive generators to generate electricity. In the hydropower station, the water in the upstream reservoir is led to the turbine through the water conduit, pushing the turbine runner to rotate and driving the generator to generate electricity. The finished water is drained downstream through the tailpipe. The higher the head and the greater the flow, the greater the output power of the turbine.
