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).
What is flooding and channeling in context with distillation?
Flooding and channeling are very significant terms with both gas absorption and distillation of it involves the use of packed towers. Flooding means that the gas velocity is very high, therefore, does not allow the flow of the liquid from the top of the tower, and flooding occurs on the top of it (ergo, the gas phase is not completely mixed by the water phase). The best gas velocity, should be half of the flooding velocity. For channeling, it is the unequal wetting of the packings in the tower. If channeling occurs, poor mass transfer happens, and therefore, less efficiency of the tower happens.
What is the difference between flooding and flash flooding?
flooding means drowning of areas by heavy rain in considerable time, but flash flooding means, heavy rain in short time.
Is it possible for a body to have acceleration when moving constant speed and constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
What velocity means?
If you have no velocity, then you aren't moving.
What are 2 means by which a mixture can be separated?
Distillation, Filtration
Why did the blood flooding began in Brazil?
blood flooding here in Brazil means Traffic of Drugs
Is it possible for a body to have an acceleration when moving with constant velocity?
No, if an object is moving with constant velocity, it is not experiencing any acceleration. Acceleration refers to a change in velocity over time, so if the velocity is constant, there is no acceleration.
Why is acceleration?
Acceleration means how fast velocity changes. "How fast" means change of velocity per time unit - and this is also called a "rate".Acceleration means how fast velocity changes.

Is there velocity when the object is at rest?
No. Velocity means speed.
Zero velocity means vehicle must be stationary?
Zero velocity means that the vehicle and the person who is measuring the velocity are moving together.
What separation technique involves using different boiling points?
Distillation is a separation technique that involves heating a mixture to separate its components based on their different boiling points. The components with lower boiling points vaporize first and can be collected and condensed back into liquid form.
Why is acceleration a rate?
Acceleration is a rate of change of velocity with respect to time. It measures how fast an object's velocity is changing, either in terms of increasing speed, decreasing speed, or changing direction. Mathematically, acceleration is defined as the derivative of velocity with respect to time.
