🔍 Key Concepts

• Impulse vs. reaction turbines and how pressure and velocity change through the nozzles and blades • How pressure distribution differs in Rateau, Curtis, and impulse‑reaction stages • The typical high‑pressure (HP) turbine stage design used to maintain more uniform exit conditions

💭 Think About

• For each turbine type listed, ask yourself: where does most of the pressure drop occur – in the nozzles, in the moving blades, or in stages? • Consider which construction gives a more gradual, continuous pressure drop through both fixed and moving blades, rather than large pressure drops only in nozzles. • Think about which design is preferred in HP stages where control of exit pressure and efficiency over a range of loads is especially important.

✅ Before You Answer

• Verify where steam pressure is highest and how it changes as it passes through the fixed nozzles and moving blades for each option. • Check which construction combines both impulse and reaction effects in the moving blades, leading to a smoother pressure gradient. • Eliminate any designs where pressure drop occurs almost entirely in the nozzles, producing mostly velocity change in the moving blades rather than significant pressure change.
