    1. The problem statement, all variables and given/known data
    A marine biology observation pod is being designed. It will be submerged, with vertical windows of various sizes and shapes. Calculate the total force being exerted on each of the windows described below. Density of water is 1000 kg/m^3

    [B]2. Relevant equations[/B]


    [B]3. The attempt at a solution
    I'm not sure if I'm doing it in right way, do I need to use integration to calculate the total force?

    How does the water pressure vary with depth ?

    Is the water pressure acting on the windows varying with depth ?

    I solve all of them except F and the professor said the final answer should be 11099.9N but I didn't get that

    You mean you that think your answer to (a) is correct?

    No, I use integration to solve them.

    So please show us what you did using integration to solve F (so we can see where to help).
