As per common design practice, the three types of hydraulic turbines, in descending order of flow rate, are

Correct answer (A) Kaplan, Francis, Pelton Solution Hydraulic turbines are classified based on their specific speed and flow rate requirements. Kaplan turbines have the highest specific speed and are designed for high flow rates at low heads. Francis turbines are medium specific speed turbines for medium flow rates and heads. Pelton wheels are low specific speed turbines designed for low flow rates at high heads. Therefore, the descending order of flow rate is Kaplan, Francis, Pelton. Turn this into a strength.
