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.
Typically, a compound's diffusion coefficient is ~10,000Ã as great in air as in water. Carbon dioxide in air has a diffusion coefficient of 16 mm 2 /s, and in water its diffusion coefficient is 0.0016 mm 2 /s.Diffusivity has an SI unit of m 2 /s (length 2 / time). In CGS units it is given in cm 2 /s.ypically, a compound's diffusion coefficient is ~10,000Ã as great in air as in water.
