Picture is included.
You are working as a summer intern for the Illinois Department of Natural Resources (DNR) and are assigned to some initial work on water resources project. The department will be overseeing the construction of a dam to create a large fresh water lake that will be approximately 18 meters deep. A horizontal pipe 1.2 meters long and 5 cm in diameter will pass through the dam at a depth of 6 meters to allow for release of the water in emergencies and for sampling. In normal situations, a plug will secure the pipe opening.
--------------------------------------------------------------------------------
(a) What will be the hydrostatic force on the plug?
How do I setup the equation for a hydrostaic force? I've tried various FBD, but none is getting me anywhere.
Ok, I know that at the same horizontal level of the pipe, the pressure is constant at that depth.
FBD of the plug shows a mg down, a bouyant force pointing to the right, and normal force up from the dam, and a foce pushing the plug down from the dam also.
So the forces in y direction cancel out. And I assume that the hydrostatic force would be the same thing as the bouyant force for this question? I am stuck and need help badly.
