Estimate capillary pressure from surface tension and curvature.
Pressure Difference (ΔP)
144.0000 Pa
ΔP = γ × (1/R₁ + 1/R₂)
The Young-Laplace equation relates the capillary pressure difference across the interface between two static fluids to surface tension and curvature.
Adjust surface tension and radii. For spherical droplets set R₁ = R₂ and toggle the checkbox.
Water: γ≈0.072 N/m, R=1 mm → ΔP ≈ 144 Pa (example).
Q: Units? A: SI (N/m, m, Pa). Q: Negative radii? A: Use positive radii magnitudes for curvature.
