Thermo1 Sheet 2

The document presents a truncated virial expansion using Pitzer correlations to calculate the second virial coefficient (B) and compressibility factor (Z) for a substance. It includes specific values for reduced temperature (Tr), reduced pressure (Pr), and acentric factor (w), along with equations for B0, B1, and Z. The final calculated values for Z and V are provided as 0.898494 and ZRT/P, respectively.
