Generally: The flooding velocity of the column is the velocity of the vapor rising through the column at which the liquid on each stage is suspended. The flow of vapor up through the column will not allow the liquid to fall down through the column causing the stages to "flood".

How does concrete or asphalt affect flooding?
Covering land with concrete or asphalt means that the rain cannot soak into the soil and instead flows along the surface. This reduces the lag time for the water to get into the river and can cause flooding as the river channel fills up much more quickly than before.
Is concentrated Ethanol blue in color?
Ethanol can reach up to 99% purity, which means highest concentration. Pure Ethanol is colorless exactly like water! Any color in ethanol is because of bad distillation or additives!
Why you calculate momentum?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
The difference between speed and velocity?
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed; Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity. The two terms are often used interchangeably.
What is deceleration measured in?
Deceleration means to decrease the velocity. The SI unit is the same as acceleration. In SI units, acceleration is measured in meters/second² (m·s-2).
