🔍 Key Concepts

• Role of a compound gage on an oily water separator (it shows vacuum/pressure related to flow restriction through the unit) • What happens to pressure differential when a separator/coalescer becomes fouled vs when it is clean • How the known condition "processed water is discharging overboard" affects which choices can still be true

💭 Think About

• If water is definitely flowing overboard, what should the pressure at the gage location look like when the internals are clean versus plugged/fouled? • In which of the choices would you logically expect the gage reading to move away from zero, and in which case might it reasonably stay at or near zero? • Which answer choices are contradicted by the statement that processed water is already discharging overboard?

✅ Before You Answer

• Look closely at where item 1 is mounted on the separator and think about whether it measures upstream, downstream, or across a restriction. • For a fouled unit, would you expect a higher than normal reading (pressure or vacuum) or a zero reading while flow continues? • Check that your choice does not conflict with the condition that water is already going overboard, which rules out any mode where discharge should be stopped or diverted.
