van der Waals surface tension formula [`van dǝr ´wȯlz `sǝr·fǝs ´ten·chǝn ´fȯr·myǝ·lǝ] THERMODYNAMICS An empirical formula for the dependence of the surface tension on temperature: γ = Kpc2/3Tc1/3(1 - T /Tc )n, where γ is the surface tension, T is the temperature, Tc and pc are the critical temperature and pressure, K is a constant, and n is a constant equal to approximately 1.23. |
