Question 1 of 27070

One of the basic rules applying to the operation of a single-pass main condenser is that the __________.

🔍 Key Concepts

• single-pass main condenser operation and purpose • relationship between cooling water temperature rise, heat transfer, and condenser vacuum • what condenser limits are practical/typical versus unrealistic or unsafe

💭 Think About

• Which option describes a reasonable, everyday operating guideline for a condenser handling seawater or river water as cooling medium? • Look at each choice: does it sound like a normal control target, an absolute limit, or something extreme/impractical for real plant operation? • How much temperature rise in cooling water is typically acceptable in a once-through system to balance heat transfer and not overheat the discharge?

✅ Before You Answer

• Compare the suggested cooling water temperature rise with what you know about heat exchangers and once-through systems • Ask whether maintaining maximum or never allowed conditions under all operating conditions sounds realistic for a marine plant • Consider whether a vacuum of 29.92 in. Hg is physically achievable in a working condenser handling exhaust steam and circulating water with dissolved gases

Question 1 of 27070

One of the basic rules applying to the operation of a single-pass main condenser is that the __________.

cooling water overboard should be about 10°F higher than the inlet temperature

vacuum must be maintained at 29.92" of Hg. under all operating conditions

quantity of reheating steam flow through the condenser must be maintained at maximum under all operating conditions

condensate temperature must never be allowed to drop below 104°F
