| 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. |
