What is a single stage impulse turbine usually called?

• A. Pelton
• B. Francis
• C. Rateau
• D. Kaplan

Answer: (C)

A single stage impulse turbine is commonly referred to as a Pelton turbine. This type of turbine is designed to utilize the kinetic energy of high-velocity water jets, which strike the turbine blades and cause them to spin. The Pelton turbine is particularly effective in applications where there is a high head of water and is characterized by its cup-shaped buckets that capture the water jet's energy. The other types mentioned serve different functions or operate on different principles. The Francis turbine is a reaction turbine that uses both kinetic and potential energy of the water, while the Kaplan turbine is specifically designed for low head hydraulic applications and also operates as a reaction turbine. The Rateau turbine is a type of impulse turbine but typically refers to a multi-stage design that incorporates a different operational approach compared to the single-stage Pelton design. Thus, in the context of single stage impulse turbines, Pelton is the correct and commonly accepted name.
