    Undergrad Which area should I use to calculate the force on a submerged surface?

    Let's say we have a tank filled with water only half way up. I want to calculate the force being applied by the liquid on one of the walls, that's F = P.A. For the area (A), should I consider the area of the entire wall (H.L), or only the area of the wall that's in contact with the liquid...

    Hydrostatics: should I use P1A1 = P2A2 or P1 = P2?

    Nope, it is not required to balance the moments in this specific problem. Thank you!

    Hydrostatics: should I use P1A1 = P2A2 or P1 = P2?

    Thank you very much! "since the pressure is a function of depth" that answers my questions.

    Hydrostatics: should I use P1A1 = P2A2 or P1 = P2?

    I used P1A1 = P2A2 and my professor said that P1=P2 is correct, but some sources on the internet say that P1A1=P2A2 is correct, just like I did, but unfortunately no one explains why one or the other is the correct answer. For P1A1 = P2A2 you get ρI / ρII = 1/4 and for P1=P2 you get ρI / ρII = 1/2.
