Two extensions of the compressibility factor Z correlation (sub

nbsp; Post up dated 8 May 2019 .  The new  Zv correlation for the direct, explicit calculation of the compressibility factor 'Z', described in the previous post,  is based on Lydersen's Chart titled: "Generalized Compressibility Factor Chart ; for Zcrit is 0.27 " is intended for use with hydrocarbon compounds, whose critical compressibility factor 'Zcrit'…
