Question 1 of 27070

In a double-effect submerged tube evaporator, the brine density should be prevented from falling below 1.5/32nds to minimize __________.

🔍 Key Concepts

• Brine density control in submerged tube evaporators • Relationship between concentration, scaling, and efficiency in distilling plants • Differences between problems caused by too high vs too low brine density

💭 Think About

• Think about what happens inside the evaporator if the brine is not concentrated enough—how does that affect heat transfer, boiling, and overall output? • Which of the listed problems is usually associated with excessively high brine density rather than low density? • In an engineering context, what operating parameter would you set a minimum limit on in order to protect performance rather than protect against damage?

✅ Before You Answer

• Identify which option is most commonly linked to high brine concentration (over‑concentration) and likely controlled by a maximum density limit, not a minimum. • Consider which effect would directly reduce the amount of freshwater produced per unit of steam if the brine is too dilute. • Ask yourself: is the 1.5/32nds value intended primarily to avoid physical damage (like corrosion or scaling) or to maintain plant performance/throughput?
