Baffles in liquid cargo tanks do not usually prevent ____ surge.
Answer: B
Side to side
Surge happens as fluids shift in a tanker. Baffles in a tanker help prevent surges to the front and to the back, but not side-to-side surges. Side-to-side surges happen when cornering. As you turn, the fluids will surge in the opposite direction of the turn and raise the center of gravity, which may result in a rollover.
All choices
- ATop to bottom
- BSide to side
- CFront to back
