*Buoyancy. The Buoyancy of abody immersed in a fluid is that property which will determine whether the body will sink, rise, or float. Archimedes established the Analysis, reasoned that the volume of an irregular solid could be found by determining the apparent loss of weight when the body is totally immersed in aliquid of known density. Archimedes Principle States: 1- The upthrust (vertical force) experienced by a body immersed in a fluid equals the weight of the displaced fluid. 2- A floating body displaces its own weight in the fluid in which it floats. vertical force F F = pressure x Alla F = P x A ppg.h But Therefore the volume VhA F = Pg. V Buoyant force can be expressed as F(b) = Wair - WLiq = dxgxVL where d is the Density of the liquid g is the acceleration of gravity and v is the volume of the immersed object Since W = m.g The apparent Change in Mass when Submerged is m - m(append) = d(liquid) x VL
