What are the separations between compartments inside tanks that have openings or holes in them called?

1. Partitions

2. Baffles

3. Dividers

4. Compartments

The correct answer is: Baffles

The term for the separations between compartments inside tanks that have openings or holes in them is "baffles." Baffles are structures used to control the movement of liquid within the tank. They help minimize the sloshing effect caused by the movement of liquid during travel, which can improve the stability of the vehicle. By allowing liquid to flow between compartments, baffles maintain a more consistent distribution of weight within the tank and enhance safety by reducing the potential for rollover. In the context of tanker trucks, baffles are particularly important as they help manage the liquid's inertia during acceleration, braking, and turning. Their design and placement within the tank must comply with specific regulations to ensure safe transportation of liquids. Understanding the function and importance of baffles in tank design is crucial for drivers, as they play a key role in maintaining vehicle stability and safety on the road.
