while applying hydrostatic pressure why the Hydrostatic acceleration should be in the opposite direction of the height?

In both the videos, it is in the upward direction

Hi

Just apply it so you get the correct pressure distr. (we do not need to think some much about it) - so if we have a positive sign on the hydr. acc., it is applied below the free surface location, as seen in the first image below, and applied above the free surface location if you use negative sign for the hydr. acceleration (see second image below).


Thank you
