What is the purpose of a fuel-oil storage tank vent?

• A. To allow for pressure equalization
• B. To circulate fuel air
• C. To disperse excess radiation
• D. To enhance temperature control

Answer: (A)

A fuel-oil storage tank vent primarily serves the purpose of allowing for pressure equalization within the tank. As fuel is drawn from or added to the tank, changes in pressure occur due to the displacement of liquid. The vent provides an outlet for air to flow in or out, ensuring that the pressure within the tank remains stable and prevents the development of a vacuum or excessive pressure. This pressure equalization is crucial for the safe operation of the tank, as it helps to avoid structural damage, leakage, or even catastrophic failure. In contrast, the other options do not accurately describe the primary function of a fuel-oil storage tank vent. Circulating fuel air is not a direct purpose of the vent, as it is more concerned with pressure maintenance than air circulation. Dispersing excess radiation is unrelated to the function of a vent, which is focused on fluid dynamics and pressure management. Similarly, enhancing temperature control is not a function of the vent itself; temperature management typically involves other systems or equipment.
