🔍 Key Concepts

• Function of the loop seal in an air ejector intercondenser and why condensate forms a seal • Normal flow path of air and steam through the air ejector and into the main condenser • What happens when a seal is broken between a low‑pressure condenser and a higher‑pressure space

💭 Think About

• Think about what the condensate in the loop seal is physically doing—what is it preventing from going where? • If the liquid barrier disappears, which way will air or vapor tend to move, considering the pressure difference? • Ask yourself: which part of the system is being protected by that loop seal, and what happens to that protection when the level is lost?

✅ Before You Answer

• Identify which component (air ejector, main condenser, or condensate flow) depends on the liquid seal for proper operation. • Confirm the direction of pressure gradient between the air ejector discharge and the main condenser. • Eliminate choices that do not directly involve the effect of breaking a seal between two pressure regions.
