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.
Sections
This section discusses fluid statics, focusing on pressure variation with depth and the principles governing fluid dynamics.
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.
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.
