We know that at the bottom of a certain tank/bottle the pressure of a fluid is high as compared to the top of the tank/bottle(assuming it to be open to atmosphere) according to the equation;
Pressure at bottom= density * 9.81 * height of tank
Then y does the fluid not go up to top of the tank/bottle since the fluid flows from high potential(pressure in this case) to lower potential??
Pressure at bottom= density * 9.81 * height of tank
Then y does the fluid not go up to top of the tank/bottle since the fluid flows from high potential(pressure in this case) to lower potential??

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.
The plural of anecdote is not "data"
RE: Flow
U talked about extra energy. If I give this energy in the form of heat, will the water from top go at the bottom ?
No. This would not happen I think. Infact the cold fluid will go up due to density difference

I meant to say that the hot fluid will go up due to density difference. (writing mistake)
I just meant to say that if heat is applied at the top, the energy level is increased but the fluid lets say water will evaoprate.

E=mgh - the fluid on the bottom will have a lower height that fluid on the top, so it stands to reason that it will have lower potential energy. so if energy flows from higher state to lower state. fluid should be going from top to bottom. not bottom to top
