🔍 Key Concepts

• Impulse vs. reaction stages in steam turbines and what causes pressure vs. velocity changes • What happens to steam pressure and velocity when it flows through nozzles or velocity-compounding stages • The purpose of velocity compounding at the high‑pressure end of a turbine

💭 Think About

• In which turbine component does the largest pressure drop normally occur: in moving blades, fixed nozzles/diaphragms, or dummy pistons? • Which option describes a setup where steam can expand and accelerate significantly before entering reaction stages? • Which choices describe components that mainly control direction or thrust rather than producing a large temperature and pressure drop?

✅ Before You Answer

• Identify which option actually contains nozzles or nozzle-like passages where steam can expand • Confirm which component is located at the high-pressure end versus the low-pressure end of the turbine • Eliminate any choice whose main function is axial thrust balancing rather than energy conversion
