Question

Multistage reaction turbines are employed to attain

• A. a large volume flow rate
• B. a large pressure drop
• C. a large mass flow rate
• D. a large area

Hint:

Reaction turbines are ideal for large mass flow applications.

Answer 1

The Correct Option is C

Multistage reaction turbines are designed to effectively handle a large mass flow rate. This is achieved through the division of the pressure drop across multiple stages within the turbine. By doing so, each stage operates with a smaller portion of the total pressure drop, which enables more efficient conversion of pressure energy into kinetic energy over the entire turbine.

This multi-stage configuration is optimal for applications requiring high mass flow rates because it allows the turbine to maintain efficiency while handling substantial volumes of fluid. Each rotor and stator pair in the turbine contributes to a gradual reduction in pressure and an increase in velocity, facilitating the handling of larger mass flow rates compared to a single-stage turbine.

Thus, the multistage arrangement is specifically suited for situations where a large mass flow rate is desired, making it a critical component in aerospace and engineering applications where efficient energy conversion is paramount.
