Questian about static pressure.
Questian about static pressure.
(OP)
They say that the static pressure at a point is equal from all directions. How can that be possible that the pressure above the point (p) is equal to the weight of water column (h1) which is directed downwards, and the pressure below that point is equal to the weight of water column (h2) which is directed upwards (refer to attached fig.)?
Thank you
Thank you

"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.

like the above post, the pressure at p is rho*g*h1, acting in all directions. thought exercise ... what direction does the pressure inside a ballooon act ?

A pressure differential in a fluid MUST result in the flow in the direction of least pressure, which is Fick's First Law of diffusion. If there is no flow and there is nothing stopping a flow, then there must not be a pressure difference.

Let's not suck Mr. Bernoulli into a statics problem. If velocity is equal to zero then the assumptions behind Bernoulli's Law are violated and any number that results is meaningless.
