Understanding Capillary Action

What is Capillary Action?

Key concepts of capillarity:

  • Surface tension driven
  • Adhesion vs cohesion
  • Contact angle effects
  • Tube radius influence

Wetting Properties

Understanding wetting:

  • Contact angle significance
  • Surface energy balance
  • Hydrophilic vs hydrophobic
  • Young's equation

Meniscus Formation

Factors affecting meniscus:

  • Surface forces
  • Gravitational effects
  • Geometric constraints
  • Material properties

Applications

Capillary action is important in:

  • Plant water transport
  • Paper chromatography
  • Microfluidic devices
  • Material testing
  • Medical diagnostics

Essential Capillary Action Formulas

Capillary Rise Height

h = 2γcos(θ)/(ρgr)

Where γ is surface tension, θ is contact angle

Wetting Force

F = γL cos(θ)

Where L is contact line length

Laplace Pressure

ΔP = 2γ/r

Pressure difference across meniscus
