Which of the freshwater generators listed below requires a source of heat and evaporates sea water at a location other than a heat exchanger surface?

🔍 Key Concepts

• Different principles of operation for reverse osmosis, evaporators, and flash-type freshwater generators • Where the actual evaporation of seawater occurs: on a heated surface vs. in a separate chamber/space • The need for an external heat source (steam, jacket water, etc.) in some freshwater generator designs

💭 Think About

• Which of these types uses pressure and membranes rather than heat to make freshwater? Eliminate that choice first. • For each remaining type, ask yourself: Does the seawater boil directly on heating tubes/plates, or is it flashed/evaporated away from the heat exchanger surface in a separate volume? • Which design is specifically known for using low pressure and preheated seawater so that it flashes into vapor when the pressure is reduced?

✅ Before You Answer

• Identify which option is not a thermal (heat-based) process at all and remove it. • For the thermal types, verify which one describes flash evaporation in a chamber rather than boiling on the tube/plate surface. • Confirm which design explicitly requires a source of heat (steam, engine jacket water) and uses that heat before the seawater is allowed to evaporate elsewhere.
