Compressibility Factor Z for sub-critical pressures for Lee-Kesler's “Simple, Normal Fluids” Z-LK with a new set of equations for Excel Spreadsheets

This post presents a set of simple, compact equations to calculate the Compressibility factor Z based on Lee-Kesler’s original publication stating: Z-LK = Z(0) + Omega * Z(1). The symbol Z(0) stands for the compressibility factor contribution of a “Simple Fluid with Zc = 0.2901” and omega is the “Acentric Factor” while Z(1) stands for…
