Fluids Pressure Upthrust and Flotation Summary

Pressure at a point in a liquid depends upon the depth and on the density of the liquid.

The pressure at any depth in a liquid acts equally in all directions.

Liquids always find their own level.

Pressure applied at any point in a confined liquid is transmitted equally in all the directions.

Archimedes' Principle - When a body is partially or wholly immersed in a fluid (liquid or gas) it experiences an upthrust which is equal to the weight of the fluid displaced by it.

Archimedes' Principle can be used to find the relative density of solids and liquids.

Apparent loss suffered by a body is equal to the upthrust exerted by the fluid.

Relative Density (R.D) of a solid

Relative Density (R.D) of a liquid

Principle of Flotation - When a body floats in a fluid, it displaces an amount of fluid equal to its own weight. The apparent weight of a floating body is zero.

Hydrometers and submarines use the principle of flotation.
