Density, Compressibility, Heating Value - GPA2172: 1996/GPA2145: 2003

This calculation is used to calculate gross heating value, relative density (real and ideal), and compressibility factor for a natural gas composition. The calculation also accounts for the effect of water.

The values of the physical constants of the Hydrocarbons used in the calculation are taken from GPA 2145-03
