Why is the danger of liquid surge more when a tank is less than full?
  • Liquid has more room to move in a partially-filled tank.
  • The air pressure is greater outside a pertially-filled tank.
  • Many semi trailer tanks are slanted so that the lower end is at the back.
  • The air pressure is greater inside a partially-filled tank.
