Hi gang,
I'm having an issue with one my homework problems. There is an L shaped tank, 3d in height, 1d in width. The verticle part of the L is 2d in height, and the horizontal part of the L is a 1d box. d = 8m _    _ _ _<Force due to pressure needed for this side. I need to find the pressure on the right wall of the horizontal part of the L. What I have managed to get so far is the equation: F=(rho)(g)(width)(height^2) Not very far, I know. I'm assuming I have to integrate this somehow, but I am unsure as to how to set it up. I'm not really looking for a solution, just a push in the right direction with regards to the integration, or in the correct direction if I am very, very wrong. Thanks, in advance, for the help.

We are actually using gauge pressure, so it simplifies the formula you gave a bit. I did get the correct answer using your method, though, so thank you very much.

Arrgh, too late!!
Oh, well. What LeonhardEuler said. I enclose a small piece of work explaining how to do these types of integrals for pressure over a submerged area. It may be useful for yourself or anyone else reading these posts.
