Question 1 of 27070

Which of the parts listed for a reaction turbine serve the same function as the nozzles of an impulse turbine?

🔍 Key Concepts

• Impulse turbine vs. reaction turbine – where does the pressure drop occur in each type? • In a reaction turbine, which passages actually accelerate the fluid like a nozzle? • Role of fixed (stator) blades vs moving (rotor) blades in directing and speeding up the flow

💭 Think About

• In an impulse turbine, the nozzles do two main jobs: convert pressure energy to velocity and direct the jet onto the rotor. In a reaction turbine, which components perform these same two jobs? • Think about where the fluid pressure is highest and lowest as it passes through a reaction turbine. In which blade passages does the fluid speed up due to pressure drop? • Do only the stationary parts act like nozzles in a reaction turbine, or do the rotating passages also contribute to accelerating the fluid?

✅ Before You Answer

• Be clear on the difference between ‘fixed’ and ‘moving’ blades (stator vs rotor). • Ask yourself: which option(s) include all the parts where pressure energy is converted to kinetic energy in a reaction turbine? • Verify whether the term ‘nozzles’ properly applies to any separate component in a reaction turbine, or whether the blade passages themselves act as the equivalent of nozzles.
