🔍 Key Concepts

• how steam should normally flow through properly seated turbine diaphragms • typical visual signs of erosion vs. leakage at a diaphragm joint • effects of moisture or carryover in multi-stage turbines

💭 Think About

• Ask yourself what physical condition would cause visible flow marks to appear across a joint line instead of evenly along the flow path. • Consider whether the symptom described points more to alignment/seating problems, to water quality/chemistry, or to normal high-temperature operation. • Think about where water would show its effects first in a turbine and what that damage typically looks like compared to a joint that is not tight.

✅ Before You Answer

• Match the words "flow marks or discoloration across the diaphragm joints" with what you know about leakage paths. • Distinguish between internal leakage at a joint and water carryover effects deeper in the stages. • Eliminate any choice that would normally cause overall blade or surface erosion rather than a clear pattern right at the joint line.
