What is a potential consequence of creating a vacuum during tank drainage?

Creating a vacuum during tank drainage can lead to physical damage to the tank. When a vacuum is formed, it causes an imbalance between the internal pressure of the tank and the external atmospheric pressure. This pressure differential can result in structural stress on the tank walls, potentially leading to deformation, buckling, or even failure, particularly if the tank is not designed to withstand such conditions.

Physical damage can manifest in various ways, such as leaks or cracks, which may compromise the integrity of the tank and lead to more significant operational issues or safety hazards. Therefore, it’s crucial to implement proper pressure management measures during tank drainage to prevent the creation of a vacuum and safeguard the structural integrity of the tank.
