Bulk Liquids & SurgeQuestion 19 of 60
On a smooth bore tanker, when is liquid surge typically the strongest?
a.When starting and stopping, because nothing slows the forward-back movement
b.Only when the tank is completely full
c.When driving at a steady speed on a straight road
d.When the parking brake is set
Explanation
Smooth bore tanks have no baffles, so the liquid surges freely forward and back when speed changes. Starting and stopping produce the strongest surge in these tanks. This is why smooth bore tanks demand smooth, gradual speed changes and extra following distance.
