The increase in weight is equal to the amount of liquid displaced by the object, which is the same as the volume of the suspended object times the density of the liquid. [ 1 ] The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. [ 2 ]
In other words, for an object floating on a liquid surface (like a boat) or floating submerged in a fluid (like a submarine in water or dirigible in air) the weight of the displaced liquid equals the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the objects weight.
Vertical pressure variation is the variation in pressure as a function of elevation.Depending on the fluid in question and the context being referred to, it may also vary significantly in dimensions perpendicular to elevation as well, and these variations have relevance in the context of pressure gradient force and its effects.

While weight fluctuations in men can be perfectly normal, if they are significant or unexpected it may be cause for concern, according to an expert. Why does my weight fluctuate so much? Skip to ...
is the density of the fluid (i.e. mass per unit volume, typically expressed in kg/m 3) g {\displaystyle g} is acceleration due to gravity (i.e. rate of change of velocity, expressed in m/s 2 ). Note that in this equation, the pressure term may be gauge pressure or absolute pressure , depending on the design of the container and whether it is ...
Weight fluctuations of five pounds are more are uncommon among men. Experts explain common sudden weight gain causes, what to do, and when to see a doctor. 12 Common Causes of Sudden Weight Gain
Pascal's law (also Pascal's principle [1] [2] [3] or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
