Prediction of Fugacity and Thermal Expansion Coefficients of SF۶ Using Second Virial Coefficient

In this paper, Fugacity and Thermal Expansion coefficients at low pressure for sulfur hexafluoride (SF۶) fluid are predicted. Also, by comparing the obtained results with experimental data, the correlation performance of second virial coefficient to predict the coefficient over a wide temperature range is evaluated. The studied correlation function is the one suggested by Zarkova et al and compared with correlation of Meng et al. The obtained results show that the correlation equation presented has a good ability to predict this property of sulfur hexafluoride
