Question 91 of 120

Why might surge feel different, and potentially more severe, in a tank without internal baffles compared to one with them?

Pick an answer

Without baffles, liquid can move more freely across the full length of the tank, creating a stronger surge
Tanks without baffles always surge less than those with baffles, since there's nothing inside to disturb the liquid's flow
Baffles have no effect on how surge feels or behaves
Surge only occurs in tanks that have baffles installed

Correct answer to question 91 (Tank Vehicles): Without baffles, liquid can move more freely across the full length of the tank, creating a stronger surge

Why

Baffles are designed to slow and break up the liquid's movement inside the tank, so a tank without them allows the liquid to move more freely across its full length, which can create a stronger, more sudden surge.
