🔍 Key Concepts

• Labyrinth seal design and how it controls fluid leakage without direct contact • Typical materials used in high-speed turbine shaft sealing at high temperature and pressure • Difference between contact seals (that rub) and non-contact seals (that rely on clearances and passages)

💭 Think About

• Which choice best matches a seal that works by creating a long, tortuous path for the fluid rather than by rubbing tightly on the shaft? • At turbine operating temperatures and speeds, which materials and constructions are most practical and durable without burning, wearing rapidly, or contaminating the system? • Which options describe more of a "packing" or rubbing seal versus a non-contact, close-clearance arrangement?

✅ Before You Answer

• Identify which option clearly describes metallic, close-clearance parts that can form grooves or fins around the shaft • Eliminate any materials that are likely to degrade at high turbine temperatures or speeds • Ask whether the description sounds like packing (contact) or a non-contact labyrinth that relies on fins/teeth and small clearances
