WebA commonly used formulation for the mixture dynamic viscosity is the exponential expression ( Chien and Ma, 1958; Dai et al., 1980; O'Brien and Julien, 1988 ). The formula is usually written as a two-parameter expression. However, here a simpler form is adopted to compute the relative dynamic viscosity as. μr = μm μw = exp(βCv) WebIn 1893 William Sutherland, an Australian physicist, published a relationship between the dynamic viscosity, , and the absolute temperature, , of an ideal gas. This formula, often called Sutherland's law, is based on kinetic theory of ideal gases and an idealized intermolecular-force potential. WebCentipoise (cP) is commonly used to describe dynamic viscosity because water at a temperature of 20°C has a viscosity of 1.002 Centipoise.
