🔍 Key Concepts

• Atmospheric drain tank function in a main condenser/distilling system • Effect of a vacuum at the tank vent while underway • Normal level control by a float-operated control valve to the condenser

💭 Think About

• Ask what it physically means if air is being drawn into the atmospheric drain tank through the vent instead of water or air being discharged. • Consider how a holed float or stuck-open control valve would change the water level and pressure in the atmospheric drain tank. • Think about whether an overflowing atmospheric drain tank would create a vacuum at the vent, or the opposite condition.

✅ Before You Answer

• Verify what pressure condition (positive pressure or vacuum) you would expect at the vent if the tank were overflowing. • Check how a damaged float (that stays down) affects the valve position and whether this would tend to raise or lower the tank level while underway. • Confirm whether an increased condenser vacuum would be a cause or an effect of a vacuum specifically at the atmospheric drain tank vent.

Question 1 of 20

Which possible condition has occurred if a vacuum is present at the atmospheric drain tank vent while the vessel is underway?

The control valve regulating flow to the main condenser is stuck in an open position.

The control valve ball float has been holed causing the ball to remain in a lowered position.

There is a definite possibility of the tank overflowing causing loss of distilled water.

There will be an increase of vacuum in the main condenser within a short period of time.
