When a tank is split into compartments by bulkheads, what effect does that have on the way the tanker handles?
Correct answer: Surge toward the front and rear is weaker than with a smooth bore tank.
Answer options
- ASurge from side to side is weaker than with a smooth bore tank
- BSurge toward the front and rear is weaker than with a smooth bore tank Correct
- CSurge is about as strong as it is with a smooth bore tank
Why
Dividing the tank with bulkheads creates smaller sections, which leaves the liquid less room to rush toward the front or back. That cuts down forward-and-back surge, so the cargo is less likely to shove the vehicle ahead when you brake.
