🔍 Key Concepts

• Difference between impulse and reaction turbines in terms of where pressure drop occurs • Meaning of pressure compounding vs velocity compounding in turbine design • How combining pressure and velocity compounding affects the number and arrangement of stages/blade rows

💭 Think About

• First, decide in an impulse turbine where the steam pressure actually drops: in the nozzles, the moving blades, or both? How does that help you eliminate any option that mentions reaction effects? • Think about what pressure-velocity compounded must mean physically: is pressure drop shared between multiple nozzle stages, multiple blade rows, or both together? • Ask yourself: if you split both pressure drop and velocity change into several steps, what would the overall stage layout (nozzles and moving blades) look like in sequence?

✅ Before You Answer

• Verify which option (if any) mixes reaction with impulse; in a pure impulse turbine, the moving blades ideally see no pressure drop. • Check which option correctly reflects more than one level of compounding: not just extra nozzles, but also extra velocity stages. • Make sure the choice you consider describes a layout that could realistically be built as multiple impulse stages with both pressure and velocity compounding, not just one or the other.
