SpletSutherland’s law, or Sutherland’s formula, is an approximation for how the viscosity of gases depends on the temperature. This law is based on an idealized intermolecular-force potential and reads ( Ref. 5) (5-7) where Sμ is an effective temperature called the Sutherland constant. Each gas has its own Sutherland constant. Splet26. jul. 2002 · Here are the constants of the Sutherland law for Helium : mu0 = 3.93267e-5 T0 = 809 C0 = 147.2. Hope it helps someone.
