NASA Gases


The following gaseous substances are defined in the NASA Program data base.   Note that some substances appear to have two names separated by a comma, e.g., C2H2,acetylene.  It is necessary to supply the name to the NASA procedure exactly as it appears in this list, including both names and the comma.  When a space or comma appears in the name, it is necessary to enclose the name within single quotes, as shown in the following example.  The names are not case-sensitive.  


h=enthalpy('C2H2,acetylene ',T=300 [K]



All of the following gases can be used  with the EES property functions.
