Question 1 of 27070

For efficient and proper operation, the brine density in a submerged tube evaporator should be maintained at __________.

🔍 Key Concepts

• Relationship between salt concentration and freezing point of brine in a submerged tube evaporator • Effect of too much salt vs too little salt on system efficiency and scale formation • Why operators care about heat transfer efficiency and scale buildup in refrigeration systems

💭 Think About

• Which option mentions a reason that actually matches what happens when salt content is too high (more dense brine) or too low? • How does brine density affect both freezing point and tendency to form scale on heat transfer surfaces? • Think about maintenance: which choice best reflects a practical operating trade-off between good refrigeration performance and reduced fouling?

✅ Before You Answer

• Compare each choice’s pounds of salt per 32 pounds of water and decide which looks like an extreme concentration versus a more moderate one • Ask: does higher salt content generally increase or decrease the chance of scale formation on tubes? • Verify which reason given in the choices (prevent excessive heat loss vs minimize scale formation) makes more sense for how submerged tube evaporators are actually maintained

Question 1 of 27070

3.5 pounds of salt per 32 pounds of water

1.5 pounds of salt per 32 pounds of water

1 pound of salt per 32 pounds of water to prevent excessive heat loss

1 pound of salt per 32 pounds of water to minimize excessive scale formation
