Question 1 of 27070

Rotor axial thrust developed in a reaction turbine is the result of a steam pressure drop across __________.

🔍 Key Concepts

• Impulse vs. reaction turbines and how thrust is created in each type • Where the steam pressure drop actually occurs in a reaction turbine stage • The roles of stationary (fixed) blades versus moving (rotor) blades in changing steam velocity and direction

💭 Think About

• In a pure impulse turbine, where does almost all of the pressure drop occur, and how does that compare to a reaction turbine? • In a reaction turbine stage, which components cause changes in pressure and which cause mainly changes in direction? • Axial thrust is tied to changes in momentum in the axial direction. In a reaction turbine, which blade set is responsible for the pressure drop that leads to this axial momentum change?

✅ Before You Answer

• Be clear on the definition of a reaction turbine versus an impulse turbine before choosing • Identify exactly where the pressure energy of the steam is converted to kinetic energy in a reaction turbine stage • Ask yourself: which blade row (stationary, moving, or both) experiences a pressure drop, not just a change in flow direction?
