Thanks for that Goest, the maths has always made sense it was just my intuition telling me maybe there is a minimum dimension needed, depending on the viscosity of the fluid. However it makes sense that if the horizontal and vertical forces are different at any point then there will be a...

if the beam is simply supported, just solve for the reactions and multiply by half by the beams length. In your case it will be 10x5/2 = +25kNm

yeah according to the maths I agree, just my intuition tells me its ridiculous that nearly 5kn can be generated on a 1x1m panel even if there is only say 50g of water between the two panels and their enclosed sides

yeah that's sort of what I am getting at, let me try to ask it another way. If I have 2 1x1m panels separated by 1cm and filled up to the top with water, will the total horizontal force be the same as if I have 2 1x1m panels separated by 1mm and filled to the top with water?

I know the maximum pressure is at the bottom, and zero at a depth of zero, which is why it is a linear load distribution on the wall. In my calculation the formula I used was derived from integration, but I did it from first principles again to reinforce...

yeah but if its a linear distribution of load then the load on the wall will be 9.81kpa x 1 x 1/2 = 4.9kN if its a 1 x 1 metre panel, as integration is basically area under the curve. Does this not sound like a ridiculous lateral load, say if the volume of water between the panels in 1x10^-6 m^3??

yeah that all makes sense, but what about that calculation I showed. It seems ridiculous that if I have 2 1x1m cantilever panels holding 0.001m^3 of water that the horizontal reaction at the base of each panel is about 4.9kN, when the total weight of the water is around 9.8N. If you extrapolate...

I just did a quick calc, say you have two glass plates each 1m x 1m, separated by 1mm. The 1mm all filled up with water. This means the vertical load is about 9.81N. If these are cantilever walls could the horizontal reaction to hold them up really be 9.81kpa x 1 x 1/2 = 4.9kN? Iv read through...

yeah that's pretty much what I mean. Is there some minimum spacing or dimension required to develop full hydrostatic pressure?

Hey guys I'm a year 12 student studying physics, and at the moment we are studying hydraulics. We learned that pressure varies with depth, which led me to this question. If I have two plates almost infinitely close together, each with a cross sectional area of A, would the total force on each...
