2 results about "Laplace pressure" patented technology

The Laplace pressure is the pressure difference between the inside and the outside of a curved surface that forms the boundary between a gas region and a liquid region. The pressure difference is caused by the surface tension of the interface between liquid and gas. The Laplace pressure is determined from the Young–Laplace equation given as ΔP≡Pᵢₙₛᵢdₑ-Pₒᵤₜₛᵢdₑ=γ(1/R₁+1/R₂), where R₁ and R₂ are the principal radii of curvature and γ (also denoted as σ) is the surface tension.
