Finds the density, relative density,
composition molecular weight, volume flow rate and mass flow rate of a
gas when the pressure, temperature and compressibility of the gas at
base and line conditions are entered.
Constants for, air compressibility,
molecular weight and density are taken from ISO6976:1983, ISO6976:1995
(E) and GPA 2172:1996. The user can specify the standard used for
constants.
