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?
