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
