What we have learnt
- Hydrostatic pressure varies linearly with depth in static fluids.
- The net force exerted by a fluid can be computed using pressure distribution diagrams.
- Surface tension and capillarity impact fluid behavior in narrow tubes.
Key Concepts
- -- Newton's Law of Viscosity
- Establishes the relationship between shear stress and the velocity gradient in fluids.
- -- Hydrostatic Pressure
- The pressure in a fluid at rest increases linearly with depth based on the fluid density and gravitational acceleration.
- -- Manometer
- An instrument used to measure the pressure of a gas or liquid, utilizing the height of a fluid column.
