Key Topics to Revise
1
Fluid Properties and Pressure
- Fluids are substances that can flow and deform continuously under applied force
- Ideal fluid: incompressible, irrotational, nonviscous, steady flow
- Pressure is normal force per unit area: P = F/A
2
Pascal's Law and Applications
- Pascal's Law: Pressure applied to enclosed fluid is transmitted equally in all directions
- Hydraulic machines work on Pascal's principle
- Force multiplication: F₂/F₁ = A₂/A₁
3
Surface Tension
- Surface tension arises due to intermolecular forces at liquid surface
- Surface acts like stretched elastic membrane
- T = F/L (force per unit length)
4
Viscosity and Fluid Motion
- Viscosity is internal friction in fluids during motion
- Coefficient of viscosity η = F/(A × dv/dx)
- Stokes' law: F = 6πηrv for spheres in viscous medium
