sci.surface-energy-Young-contact Calculator
Calculates equilibrium contact angle using Young's equation: cos θ = (γ_SV − γ_SL)/γ_LV, and work of adhesion W = γ_LV(1 + cos θ). Superhydrophobic surfaces (θ > 150°) have W < 0.1 mJ/m² — self-cleaning surfaces require W < 10 mJ/m², achievable with micro/nano surface textures that trap air.
Inputs
Theta Deg
Reference formula or conversion factor shown for context.
Gamma Lv Mn M
Capacity to do work (J or kWh). Conserved — converts between forms but total stays constant in a closed system.
Gamma Sv Mn M
Capacity to do work (J or kWh). Conserved — converts between forms but total stays constant in a closed system.
