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.
