Hello,world

I already started this thread on this page Pressure on a lateral side of a tank - Page 2

but the discission stopped and i'm still confused so I hope you spend some time reading the thread

My question:Or to put it another way,

Total force on lateral surface = (area of surface) * (average pressure on the surface)

... and the average pressure is the pressure half way up the side.

Acoording to your equation:the pressure applied at any point on the lateral surface equals to the average pressure.and by multiplying pressure-force per unit area-times the whole area,thus we get the total force applied on the lateral wall.

and that's not true beacuse the pressure varies along the lateral surface

Could you realise my problem?

Thanks

and this is my post answering the question I asked :

Is that true?Well,okay,may be you mean that force is still the same whatever the way we distribute it.

read the latest posts in the thread above and tell me If I'm on the right way or not.

may be my main problem is that i can't really differniate between force and pressure

Thanks in advance
