The efficiency of a flash type evaporator can be increased by __________.

Question 1 of 27070

The efficiency of a flash type evaporator can be increased by __________.

🔍 Key Concepts

• flash type evaporator operation and purpose • relationship between pressure, temperature, and boiling point of water • how multi-stage evaporation improves efficiency

💭 Think About

• Think about what change would let water boil at a lower temperature in each stage, using the same heat more than once. • Consider which options would reduce the overall energy needed to turn seawater into vapor, rather than just changing flow conditions. • Ask yourself: in a multi‑stage system, what lets later stages use the remaining heat from earlier stages more effectively?

✅ Before You Answer

• Verify which option directly affects absolute pressure in the stages and how that changes the boiling point. • Check which changes simply increase mechanical/flow losses instead of improving thermal efficiency. • Confirm which choice best supports using latent heat of vaporization multiple times across stages.
