## Homework Statement:

- Understanding the Force / Pressure Equation along a wall and across a surface area

## Homework Equations:

- p = density * gravity * Distance from the water surface.

Hello all

I am trying to understand the pressure equation.

I have the following question:-

I understand this, to me what this says to me is the total force acting on the wall as a result of the water of 12m is 706320 Pascals.

This is where I get a little confused, I have the following question:-

Now I am asked to calculate the total force on a surface area of a wall and because of this I have been told to use a difference equation which involves w i.e. the width.

Am I correct in thinking that the reason why the equations are different is because the first question is only asking me to find the total force in 1 dimension whereas the second question I am asked to find the force across an area which is in 2 dimensions

Is this correct?

Thank you.
