🔍 Key Concepts

• Operation of a low pressure multi-effect distilling plant • Effect of shell pressure stability vs. fluctuation on evaporation and condensation • Relationship between brine density (salinity) and plant performance/scale formation limits

💭 Think About

• Think about what the last effect shell is supposed to do in a multi‑effect evaporator. Does it work better with a stable vacuum/pressure or with rapid pressure changes? • Consider what happens to evaporation rate and heat transfer if the pressure in the last effect is held very steady versus if it fluctuates. • For the brine options, ask: is lower salinity (lower density) or higher salinity (higher density) normally more of a concern for scaling and efficiency loss in distilling plants?

✅ Before You Answer

• Identify whether steady pressure in a low‑pressure evaporator generally helps or hurts overall efficiency and output. • Recall the usual maximum brine density limit (given in the choices) and whether exceeding or not reaching that limit is associated with reduced capacity or operational safety. • Decide which factor, pressure behavior or brine density level, would more directly and immediately reduce the evaporation/production rate in the last effect.
