Why is a full tank less susceptible to surge than a partially loaded one?
a.Full tanks have more baffles
b.When a tank is full, there is very little room for the liquid to move
c.Full tanks are always pressurized
d.The liquid is heavier when the tank is full
Explanation
When a tank is completely full (with proper outage), there is very little room for the liquid to move. The liquid cannot build up momentum because it has nowhere to go. In a partially filled tank, the liquid has room to slosh and surge, creating more force against the tank walls.
