WebFeb 2, 2011 · Einstein's result for the diffusion coefficient D of a spherical particle of radius a in a fluid of dynamic viscosity h at absolute temperature T is: where is the gas constant and N A is Avogadro's Number. The formula is historically important since it was used to make the first absolute measurement of NA so confirming molecular theory. WebIn fluid mechanics, hydrostatic equilibrium (hydrostatic balance, hydrostasy) is the condition of a fluid or plastic solid at rest, which occurs when external forces, such as gravity, are balanced by a pressure-gradient force. In the planetary physics of Earth, the pressure-gradient force prevents gravity from collapsing the planetary atmosphere into a …
