why water doesnt flow from bottom to top of a vessel though pressure there is higher?

Question

The vessel is open to atmosphere.Another similar question is that how can water flow from the throat of a venturimeter to its exit though pressure at exit is higher than pressure at throat.

Answer 1

There is no potential energy driving a current from the bottom to the top (unless there are density differences). Any displacement of matter from the bottom would have to be counterbalanced by displacement of material from the top to the bottom. Perpetual motion without input of energy doesn't exist.

In a venturi in the high velocity area pressure is converted into kinetic energy and then converted back into pressure as the material slows down.

Answer 2

Gravitation, the force of attraction between all objects that tends to pull them toward one another. It is a universal force, affecting the largest and smallest objects, all forms of matter, and energy. Gravitation governs the motion of astronomical bodies. It keeps the moon in orbit around the earth and keeps the earth and the other planets of the solar system in orbit around the sun. On a larger scale, it governs the motion of stars and slows the outward expansion of the entire universe because of the inward attraction of galaxies to other galaxies. Typically the term gravitation refers to the force in general, and the term gravity refers to the earth's gravitational pull.
Gravitation is one of the four fundamental forces of nature, along with electromagnetism and the weak and strong nuclear forces, which hold together the particles that make up atoms. Gravitation is by far the weakest of these forces and, as a result, is not important in the interactions of atoms and nuclear particles or even of moderate-sized objects, such as people or cars. Gravitation is important only when very large objects, such as planets, are involved. This is true for several reasons. First, the force of gravitation reaches great distances, while nuclear forces operate only over extremely short distances and decrease in strength very rapidly as distance increases. Second, gravitation is always attractive. In contrast, electromagnetic forces between particles can be repulsive or attractive depending on whether the particles both have a positive or negative electrical charge, or they have opposite electrical charges. These attractive and repulsive forces tend to cancel each other out, leaving only a weak net force. Gravitation has no repulsive force and, therefore, no such cancellation or weakening.
The gravitational attraction of objects for one another is the easiest fundamental force to observe and was the first fundamental force to be described with a complete mathematical theory by the English physicist and mathematician Sir Isaac Newton. A more accurate theory called general relativity was formulated early in the 20th century by the German-born American physicist Albert Einstein. Scientists recognize that even this theory is not correct for describing how gravitation works in certain circumstances, and they continue to search for an improved theory.

Answer 3

this is an example of an hydrostatic pressure, meaning the pressure is at rest hence even there is a great pressure below the vessel it will not affect the water to rise.

Answer 4

I would like to see the view from the top as long as it isn't on top off a really fat women. I am tired of being sandwiched in between bad moments in life.

Answer 5

Have u heard of GRAVITY?!
