A substance that flows is called a fluid. Fluids exert pressure on the base and walls of the container in which they are enclosed. Pressure exerted in any confined mass of fluid is transmitted uniformly in all directions.
Laws of Liquid Pressure (Pressure in Fluids)
- Pressure is the same in all directions about a point in the liquid.
- In a stationary liquid, the pressure is the same at all points on a horizontal plane.
- Pressure at a point inside the liquid increases with depth from the free surface.
- Pressure at the same depth is different in different liquids. It increases with an increase in density.
- A liquid seeks its own level.
