Water Pressure - Horizontal or Lateral

[2know]

Water weighs about 6lbs per gallon. So if one has a column of water, say, at 10 gallons, the pressure over an area is about 60lbs. This can be deduced to pounds per square inches.

Question:

How much pressure, per square inch, does water exert on a vertical wall such as a swimming pool? Does the pressure change if the wall is not vertcal but, say, at 45 degrees?

[Janus]

The pressure on a vertical wall of a swimming pool depends on the depth at which you measure it.

At any given depth, the pressure is the same in all directions; vertical, horizontal, or anything in between.
