Just wondering if the Betz limit is applicable to hydro turbines or if there is some analogous limit for hydro turbines?

The Betz Limit is a theoretical maximum efficiency that a hydro turbine can achieve when converting the kinetic energy of water into mechanical energy. It was first proposed by German physicist Albert Betz in 1919.
The Betz Limit is calculated by dividing the power output of the turbine by the power available in the water flow. This results in a maximum efficiency of 59.3%, meaning that no turbine can convert more than 59.3% of the available energy in the water into mechanical energy.
The Betz Limit is important in hydro turbine design because it sets a theoretical upper limit for the efficiency of the turbine. This allows engineers to determine the maximum potential of a hydro turbine and make design choices that can optimize its efficiency.
No, a hydro turbine can never achieve 100% efficiency due to the laws of thermodynamics. The Betz Limit represents the maximum efficiency that can be achieved, and even with perfect design and operation, some energy will always be lost due to factors such as friction and turbulence.
The Betz Limit can be improved upon by making design improvements to the hydro turbine, such as reducing friction and turbulence, and by finding ways to capture and convert more of the available energy in the water flow. Additionally, combining multiple turbines in a series or parallel configuration can also increase overall efficiency.
