Surface Tension

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

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 formula

\(\large{ \sigma = \frac{F}{l}   }\) 
Symbol English Metric
\(\large{ \sigma }\)  (Greek symbol sigma) = surface tension \(\large{\frac{lbf}{ft}}\) \(\large{\frac{N}{m}}\)
\(\large{ F }\) = force per unit length \(\large{ lbf }\) \(\large{N}\)
\(\large{ l }\) = length in which force acts \(\large{ ft }\) \(\large{ m }\)
