BUOY

How far will the oil drum pontoons on your raft sink into the water if you try to float your lathe? How deep will a lead cricket ball float in a pool of mercury? Answer these and other equally burning questions with this tool for calculating buoy immersion depth as a function of applied load.
The upward buoyant force on a buoy is equal to the weight of the liquid displaced when the buoy is immersed. In turn, this weight is equal to the volume of the buoy below the liquid surface multiplied by the density of the liquid in which it is immersed.
The buoy sinks into the liquid to such a point that the upward buoyant force is just equal to the weight of the buoy plus any load that the buoy supports.
Given the pertinent information mentioned above (liquid density, buoy geometry and buoy weight plus load), the program was designed to return the bouy immersion depth.
