SpletThis formula, often called Sutherland's law, is based on kinetic theory of ideal gases and an idealized intermolecular-force potential. Sutherland's law is still commonly used and most often gives fairly accurate results with an error less than a few percent over a wide range … SpletThe Sutherland-Einstein equation has very often been used to obtain information about the radii of the diffusing molecules from the observed values of their diffusion coefficients. In the case of translational free diffusion of neutral molecules the driving force per mole is the negative gradient of the chemical potential. SpletThe parameters in Sutherland’s formula are as follows: To = reference temperature, K μo = viscosity of the gas at temperature, To C = Sutherland’s constant for the gas, K T = the temperature of the gas, K μ = the viscosity of the gas at temperature, T, in the same units as μo.

Spletlaw. Now, from the definition of absolute mobility, i.e., ̅ = (63) The drift velocity can be divided either by the diffusional driving force or by the equal and opposite viscous force given by Stokes law. Therefore, using equation (61) in equation (63), we get ̅ … SpletTherefore, in one dimension, the equation can be represented as: Qcond= kA (T1 − T2 / Δx) = −kA (ΔT / Δx) If Δx 0, the equation in differential form can be written as: Qcond = −kA (ΔT / Δx) Thus, the 3-dimensional form of Fourier’s law is: q = - k\(\bigtriangledown\)T Fourier’s Law Also Read:Branches of Physics Important Forms of Fourier’s Law

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.
