🔍 Key Concepts

• Flow paths of brine, feedwater, and distillate in a low‑pressure flash evaporator • Where the brine eductor picks up concentrated brine from the evaporator shell • Difference between a line that is an inlet to the unit versus a suction to a pump or eductor

💭 Think About

• Trace where the seawater enters the unit, where it is heated, and where the concentrated brine must leave the shell • Look at which component line K is physically connected to on the rear view: is it tied to the evaporator shell, the distillate pump, or the eductor body? • Ask yourself: from this point in the system, is fluid being supplied TO the evaporator, or is it being DRAWN AWAY by another device?

✅ Before You Answer

• Verify whether line K connects directly to the eductor body or to a heater/feed connection • Check if line K is located near the concentrated brine collection area at the lower part of the shell, where brine would be removed • Confirm whether line K is on the suction side (throat) of the eductor or on a pressure/ discharge side; this will distinguish between an inlet and a suction connection
