PREPARATION OF A GENERALIZED CHART FOR THE DIFFUSION COEFFICIENTS OF GASES AT HIGH PRESSURES

[摘要] References(36)Cited-By(77)A new generalized chart analogous to that of Slattery and Bird (SB chart) was prepared from the observed values of the self- and binary-diffusion coefficients of gases at high pressures. The deviation of the values produced by the new chart from those observed is 4.1% on the average, whereas that of the values produced by the SB chart is 7.9%. In addition the new chart gives the average of the values observed, whereas the SB chart gives lower values for most of the systems.
