Fuller's equation Fuller's equation is an empirical equation that is also used at low pressures. The equation may be used for nopolar gas mixtures and polar-nonpolar mixtures [2]. The equation is less reliable than that of Hirschfelder equation described above. 1/2 10-T 75 DAB +. MA MB Use T in K. p in atm, o from the table gven on the next slide. D will be in cm/s. AB
