Quick revision notes for Mechanical Properties of Fluids — CBSE Class 11 Physics. Key concepts, formulas, and definitions for last-minute revision.
Key Topics to Revise
Introduction to Fluids
- Fluids include both liquids and gases that can flow
- Liquids: incompressible, fixed volume, free surface
- Gases: compressible, no fixed volume, fill entire container
Pressure in Fluids
- Pressure is force per unit area acting normal to the surface
- Fluid exerts force perpendicular to any surface in contact
- Pressure is scalar quantity with dimensions [ML⁻¹T⁻²]
Pascal's Law and Pressure Variation
- Pascal's Law: Pressure applied to enclosed fluid transmits equally in all directions
- Pressure is same at all points at same horizontal level in fluid at rest
- Pressure increases with depth due to weight of fluid column
Fluid Flow and Streamlines
- Steady flow: velocity at each point remains constant with time
- Streamline: path followed by fluid particle in steady flow
- No two streamlines can intersect in steady flow
