What is the normal pressure of a small turbine wheel in Pa?

The normal wheel pressure of a small turbine is 5 MPa. A hydroturbine is an electrical machine that converts the energy of water flow into rotating mechanical energy. It is a turbine machine among fluid machines. As early as around 100 BC, the prototype of a hydraulic turbine – a waterwheel – appeared in China, used to lift irrigation and drive grain processing equipment. Modern hydraulic turbines are mainly installed in hydroelectric power stations and are used to drive generators to produce electricity. In a hydroelectric power station, water from the upstream reservoir is directed to the turbine via the bypass pipe, pushing the turbine wheel to rotate and driving the generator to produce electricity. The water that has finished its work is discharged downstream through the tailrace. The higher the water height and flow rate, the higher the power output of theturbine is high.
