I have a question that has me questioning the laws of fluid physics. I will
be posting the question in a day or so, but first I want to get some others
input regarding water pressure at different depths. First, do we all agree
that pressure is only dependant on depth of water? Lets say you had an
aquarium that was 3 feet high and 3 feet long and 2 feet front to back.
Fluid laws say it would not matter what the front to back measurement is.
The pressure on the front glass would be the same if the back of the
aquarium was two feet or 200 feet or 200 miles away, right?

That's correct. Otherwise dams on rivers like the Colorado would
burst.

Notwithstanding:
- density of the water (salt, fresh...)
- Pressure at the surface of the water (ie we're talking differential
pressure, open tank)
- Changes to gravity, either from location (earth vs moon), acceleration,
or maybe Kurt Vonnigut is right and the gravitational "constant" isn't...
