In this spreadsheet, just type in the required information
and press the compute button. Scroll down for more info.
* Note 1: (Ppc, Tpc) and Mol. Weight are mutually exclusive.
Enter 0 for the ones you don't need.
** Note 2: A small change, say 10 psi
Gas Coefficient of Isothermal Compressibility
Cg = 1/p - 1/z *(Delta z/Delta p)
Cg = Coefficient of isothermal compressibility, 1/psi,
p = pressure of interest, psia,
z = gas Z factor at p,
Delta p = a small change of p, psia,
Delta z = change of z corresponding to Delta p. This change is calculated
