Surface Tension

surface tension 1Surface tension, abbreviated as \( \sigma \) (Greek symbol sigma), is the energy or force at the surface of a liquid that holds it together.


Surface Tension formulas

\(\large{ \sigma = \frac{F}{l}   }\)   
\(\large{ \sigma =   \frac{ \rho \; v^2 \; l_c }{ We }   }\)  (Weber number


\(\large{ \sigma }\)  (Greek symbol sigma) = surface tension

\(\large{ l_c }\) = characteristic length

\(\large{ \rho }\)  (Greek symbol rho) = density of mass

\(\large{ F }\) = force per unit length

\(\large{ l }\) = length of a surface areas that keep sliding side stationary

\(\large{ v }\) = velocity of fluid

\(\large{ We }\) = Weber number
