🔍 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.
