Distillation principle questions

Distillation principle question: Why must there be a height difference of at least 3 meters between the condenser at the top of the distillation tower and the top of the tower itself?
Natural backflow or forced backflow; therefore, a high pressure difference is required to achieve this
This is the naturally returning condensed liquid
Since it is a natural backflow, it is necessary to ensure that the pressure difference allows for backflow to the tower on its own. With a pump, it can be placed at a position lower than the top of the tower
