when the fluid passed through pipeline，it impacts the turbine blade and produces
driving torque on the turbine, the turbine produce spin by overcoming friction torque and fluid resistance moment.In a constant
flow range,For some fluid medium viscosity,the turbine’s rotational angular velocity and fluid velocity is in direct proportion。

Therefore, the fluid speed can be got by the rotational angular velocity, the fluid flow can be calculated as well.
