A "Francis turbine" is a type of water turbine that's used to generate electricity in hydroelectric power plants. It's designed to efficiently convert the energy of flowing water into mechanical energy, which then drives a generator to produce electricity. Imagine a giant water wheel, but much more sophisticated and efficient. Francis turbines are versatile and can operate over a wide range of water flow rates and heights. They are one of the most common types of turbines used in hydroelectric plants worldwide.
