3. Basics of fluid mechanics - I (Contd.)
The chapter delves into fluid statics, particularly the variation of pressure with depth in a liquid. It discusses how pressure exerted by a fluid increases with depth due to the weight of the fluid above and emphasizes the principles of Pascal's law. The implications of pressure variation are explored in the context of practical applications, such as dam design and atmospheric pressure measurement.

What we have learnt
- Pressure in a liquid increases with depth due to the weight of the fluid above.
- Pressure is exerted perpendicular to surfaces and depends only on depth, not on direction.
- Barometers measure atmospheric pressure through the height of a liquid column supported by atmospheric force.
Key Concepts
- -- Fluid Statics
- The study of fluids at rest and the forces exerted by fluids on surfaces.
- -- Pascal's Law
- A principle stating that pressure applied to a confined fluid is transmitted undiminished in every direction throughout the fluid.
- -- Hydrostatic Pressure
- The pressure exerted by a fluid due to the weight of the fluid above it, which increases with depth.
- -- Barometer
- An instrument that measures atmospheric pressure using a column of liquid.
