All factors affect a volumetric tank test except which?

All factors affect a volumetric tank test except which?

• A. Height and temperature of groundwater
• B. Waiting periods after deliveries
• C. Tank geometry
• D. Evaporation

Answer: (A)

Volumetric tank testing measures tightness by tracking the amount of water contained in the tank and any loss over a set period to identify leaks. The key factors that influence the readings are how much water the tank geometry can hold, whether air pockets have been purged after deliveries, and how much water is lost to evaporation during the test. The external height or temperature of groundwater doesn’t change the amount of water inside the tank or the rate at which water leaves the tank through its walls in this type of measurement, so it doesn’t affect the volumetric test outcome.
