A smooth bore tank is also referred to as what?

A smooth bore tank is correctly referred to as an un-baffled liquid tank. This designation is important because un-baffled tanks do not have any internal structures to disrupt the flow of liquid. This design allows for a smooth, unobstructed passage, which is essential for certain types of liquid transport, particularly for materials that can slosh or surge during transport.

In contrast, baffle tanks contain internal baffles that help control the movement of liquid, reduce sloshing, and stabilize the load. Pressure vessels are designed to withstand high pressures and are not specifically linked to the concept of smoothness or the absence of baffles. A closed container simply signifies that the tank is sealed but does not provide specific information regarding the internal structure or design like the term "un-baffled" does. Therefore, emphasizing that a smooth bore tank is an un-baffled liquid tank clarifies its characteristics and operational implications in transport scenarios.
