🔍 Key Concepts

• Relationship between pump discharge and where the fluid is going in an evaporator/distilling plant system • Differences in location and purpose between brine, distillate, and condensate lines • How the ejector supply line is routed relative to the seawater inlet and vacuum equipment

💭 Think About

• Trace the letter S line on the rear view: where does it start and where does it go in the system? • Compare the connection points of lines marked P, T, U, and S – which pumps are they associated with, and what does each pump normally handle? • Think about which discharge line would logically be at that height and position on the unit: would brine, distillate, condensate, or ejector supply be located there?

✅ Before You Answer

• Verify which pump casing or component the line S is physically attached to – that tells you whose discharge it must be • Confirm where that line ultimately leads (overboard, to a tank, to an ejector nozzle, or back into the shell) • Make sure you distinguish between suction and discharge sides of each pump before choosing your answer
