While answering this question on DIY.SE, I wanted to calculate the amount of pressure (in psi) that would be exerted on the walls of the container. However, I don't know much about how to calculate such pressures.
Assume the interior of the container is solid (e.g. covered in plywood and a rubber liner)
Container outside dimensions: 8' x 8' x 3'
Container inside dimensions: 89" x 89" x 36"
Container volume: 165.020917824 cubic feet (
(89x89x36) x 0.000578704)
Amount of water held by container : 1234.521486241344 gallons (
165.020917824 x 7.481)
Weight of water held by container : 10,297.3052722176 pounds (
165.020917824 x 62.4)
How would I calculate the amount of pressure on the walls in pounds per square inch?
