Which statement correctly distinguishes bulkheads from baffles in a liquid tank?
Correct answer: C – Bulkheads can divide the tank into compartments; baffles are bulkheads with holes that permit liquid flow.
Bulkheads divide some liquid tanks into several smaller compartments. In a baffled tank, the internal bulkheads contain holes that allow liquid to flow through and help reduce forward-and-back surge. Baffles do not prevent side-to-side surge, which can still contribute to a rollover.
