Let's say I have a fish tank with a total volume of 0.25m3 (100x50x50cm) filled with 160l of water. There's no lid and the thing is placed in a room with sea level atmospheric pressure. The whole thing hasn't been moved for a while so the water is absolutely calm.
Now, if I were to lift the tank by 3cm in a seesaw motion in order for the water to start flowing and forming a wave, how would I go about calculating the maximum pressure the water puts on the walls?
Of course I'd wait for a fixed amount of time before lifting the other side of the tank so the wave stays the same in height.
I think I could do the calculations myself but I have no idea where to start or even where to look for a hint (piston pressure? mass inertia? Bernoulli's equation?).
The reason I need this (or at least I think so) is to calculate the wall thickness. It's basically like a wave motion machine, but open and filled with water: Photo
