diffusion coefficient see diffusion coefficient. coefficient of digestibility the proportion of a food that is digested compared to what is absorbed, expressed as a percentage. dilution coefficient a number that expresses the effectiveness of a disinfectant for a given organism.
The diffusion coefficient for a mixture can be calculated from: Source: Wilke (1950)3; as cited in Welty et al., 1984. Substituting the values from Table 1 in equation (3), we can calculate the diffusion constant for oxygen in a mixture of these gases, given the mole fraction of each. The results of this calculation are provided in Table 2, for variations of O2, relative humidity, and temperature.
