🔍 Key Concepts

• Difference between impulse turbines and reaction turbines • Types of steam losses in turbines (internal vs external) • Where steam pressure drops occur in impulse stages (nozzles, moving blades, clearances)

💭 Think About

• Think about which loss would be uniquely associated with the construction details of an impulse turbine stage, not common to both types • Ask yourself: in an impulse turbine, where does high-pressure steam tend to leak or escape that is less of an issue in a reaction turbine? • Consider which option refers to a part or feature that is characteristic of impulse stages (nozzle & diaphragm arrangements)

✅ Before You Answer

• Eliminate any losses that would clearly apply to both impulse and reaction turbines equally • Check which option is linked to stage diaphragms and segment joints, a common design feature in impulse stages • Verify which loss is associated with steam leakage around stationary blade carriers rather than through the blades themselves
