I clarified it to clear the misunderstanding(if any) of future viewers of this thread. PS: I know that you are perfectly aware of this from your first post on 8th September. Vertical section may not fail if we design the tank as per the pressure calculated by your method but bottom horizontal section may fail. This calculation is generally not useful for designing thickness of tanks, for the tank should be designed for the maximum pressure possible in the system i.e at the bottom most section of the tank. Find the fluid force on one side of the rectangular plate, where the dimensions are given in feet, and the tank is full of water (62.4 lbs/cu.ft.) arrowforward Find the fluid force on the vertical plate submerged in water, where the dimensions are given in meters and the weight-density of water is 9800 newtons per cubic meter.
This calculation is generally used when we have to design hinged (or other)closures. Secondly, integration yields net pressure and net force on the tank wall and this acts at about 2/3rd height from the top of the tank. That is why I considered P 0 as redundant. In my experience, all water tanks are atmospheric. You come up with better knowledge whenever you are teased, yet never losing your temper.Ĭoming to the OP, I presumed, here, many things. I like even being devil's advocate with you.
