Question 1 of 205eccef9cbacbc34ba4d45774

The vent line from the main condenser water boxes was not opened when the waterside was recharged. This would __________. lead to vapor binding of the main circulating pump contribute to a higher than normal condensate temperature entering the air ejector condenser

🔍 Key Concepts

• Role of vent lines on condenser water boxes and what happens if air is trapped in the waterside • How vapor binding occurs in a centrifugal circulating pump and what conditions are needed for it to happen • Effect of reduced heat transfer surface (due to air pockets) on condensate temperature and condenser performance

💭 Think About

• Think about what physically happens inside the water boxes and tubes if the vent line is not opened and air remains trapped when filling the system with cooling water. • Ask yourself: does trapped air at the high points of the cooling water side help or harm the ability of the circulating pump to stay fully flooded? • Consider whether warmer condensate entering the air ejector condenser would more likely result from poor cooling water circulation or from something happening on the steam side instead.

✅ Before You Answer

• Verify whether air pockets on the cooling water side can cause loss of prime or vapor binding in a centrifugal pump. • Check if reduced effective cooling water flow or surface area would raise the condensate temperature before it reaches the air ejector condenser. • Confirm whether each statement (I and II) is a direct consequence of not opening the vent line, or if another condition must also be present.
