Fluild mechanics

    1. The problem statement, all variables and given/known data

    Question 1. Water is stored either side of a vertical lock gate as shown in Figure Q1 The water level on one side of the wall is 10.0 m, on the other side it is 4.0 m. Determine the net force on the wall, per metre length, and the location of the point of action of the force.
    10.0
    4.0

    2. Relevant equations

    Bernoulli's Equation


    3. The attempt at a solution

    I wasn't sure at all how to answer the question

    Is there meant to be a diagram attached?

    This looks like a hydrostatics question so Bernoulli's eqn is not what you want.

    Welcome to the PF.

    If you could scan & post a copy of the figure being referenced, that would help out some. And what do you mean by Bernoulli's Equation being the only relevant equation?

    So it sounds like you need to figure out the pressure difference on the wall at each height h, and integrate the difference in forces on the wall from the bottom to the top. Does that make any sense?
