Which of the following statements represents the function the nozzle assembly performs in an impulse turbine?

Question 1 of 27070

Which of the following statements represents the function the nozzle assembly performs in an impulse turbine?

🔍 Key Concepts

• Impulse turbine basic operating principle • Role of the nozzle vs. the rotor blades in an impulse stage • Where pressure drop and velocity increase occur in an impulse turbine

💭 Think About

• In an impulse stage, ask yourself: in which component does the steam actually expand and gain speed? • What is the specific job of the fixed nozzles compared with the moving blades? • Which choice correctly describes energy changing form (thermal, potential, kinetic) in the part that is stationary?

✅ Before You Answer

• Verify which component in an impulse turbine is responsible for the major pressure drop. • Confirm that in a pure impulse turbine the rotor blades ideally see velocity change but little or no pressure drop. • Eliminate any option that suggests the nozzle prevents steam from expanding or increases pressure before the rotor.

Question 1 of 27070

Which of the following statements represents the function the nozzle assembly performs in an impulse turbine?

Converts the steam's thermal energy into kinetic energy by increasing its velocity and directing it against the rotor blades.

Provides an area where the steam is prevented from expanding prior to being directed against the rotor blades.

Increases the velocity of the steam without a pressure drop across the diaphragm.

Converts the potential energy of steam into thermal energy by increasing its pressure and directing it against the turbine blades.
