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.
