Homework Help: Water Pressure - Horizontal or Lateral

  1. Apr 9, 2006 #1
    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.


    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?

    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.
