Calculate Surface Tension

About Young-Laplace Equation

The Young-Laplace equation describes the pressure difference across a curved surface due to surface tension. It's fundamental in understanding capillary phenomena and fluid mechanics.

General Form:

ΔP = γ(1/R₁ + 1/R₂)

Spherical Surface:

ΔP = 2γ/R

Cylindrical Surface:

ΔP = γ/R

Capillary Rise:

γ = (ρghr)/(2cosθ)

Where:

  • ΔP = Pressure difference
  • γ = Surface tension
  • R₁, R₂ = Principal radii of curvature
  • R = Radius of curvature
  • ρ = Liquid density
  • g = Gravitational acceleration
  • h = Capillary rise height
  • θ = Contact angle

Applications:

• Capillary action
• Bubble formation
• Drop formation
• Wetting phenomena

Examples:

• Water rising in plants
• Inkjet printing
• Microfluidics
• Surface coatings

The Young-Laplace equation is essential in understanding surface phenomena, microfluidics, and biological processes involving liquid interfaces.
