In what way does driving a smooth bore tanker differ from driving one with baffles?
Correct answer: Front-to-back surge is much stronger, since nothing slows the liquid.
Answer options
- AThey weigh more, so they must stay under lower legal weight limits
- BFront-to-back surge disappears, since the liquid can move freely
- CFront-to-back surge is much stronger, since nothing slows the liquid Correct
Why
A smooth bore tank has no baffles at all, so the liquid can rush the whole length of the tank each time the truck speeds up or slows down. The resulting front-to-back surge is very strong, which is why starts and stops demand extra care.
