🔍 Key Concepts

• Trace the vapor flow paths shown by the dashed lines from sections "G" and "F" and note where they pass relative to device "C". • Consider the purpose of a division plate or baffle between two stages in a distilling/evaporator unit (pressure, flow direction, phase separation). • Compare what components usually remove moisture from vapor (their shapes and locations) versus what components control vapor production (heating/temperature-related).

💭 Think About

• Look at how the dashed red and green flow arrows interact with device "C". Does "C" seem to be something vapors pass through, around, or does it simply separate spaces? • Ask which section ("F" or "G") device "C" is actually in. Does its location match something that would access a compartment, control boiling, dry vapor, or change pressure between stages? • Think about a two-stage distiller: why might you want a pressure difference between the upper and lower stages, and what kind of structural feature would create that difference?

✅ Before You Answer

• Verify whether vapors physically contact or pass through device "C" (would be necessary for moisture removal or vapor control). • Check if device "C" has any moving parts, valves, or openings that would allow access or active control, or if it is a fixed plate or wall. • Confirm whether device "C" lies exactly between sections "F" and "G", acting as a separator, and what effect that has on pressure and flow.
