Use TQSTXP to get the calculated thermodynamic properties of a stream.
Added for ChemApp version 1.1.3
FORTRAN: CALL TQSTXP(IDENTS,OPTION,VAL,NOERR)
C: tqstxp(idents,option,&val,&noerr)
;
Pascal: tqstxp(idents,option,val,noerr)
;
Basic: Call tqstxp(idents,option,val,noerr)
Name | Type | Value set on call or returned |
IDENTS | CHARACTER | Set to the name of a stream |
OPTION | CHARACTER | Set to a string as shown in Table 20 |
VAL | DOUBLE PRECISION | Returns the value of the thermodynamic quantity |
NOERR | INTEGER | Returns an error number |
IDENTS and OPTION are both input. IDENTS is a name previously defined by calling TQSTTP. OPTION is character input identifying the thermodynamic quantity (see Table 20). The subroutine returns the value of the desired thermodynamic quantity through VAL, using the currently selected system units. See also the notes in Appendix B.1 for more information on how the extensive properties are calculated.
For users of ChemApp versions prior to 3.2.0: Please note that the values returned by TQSTXP always refer to the last calculated equilibrium state. If TQSTXP is called before the first equilibrium calculation has been performed using TQCE or TQMAP, VAL will be zero.
As of ChemApp version 3.2.0, TQSTXP can be called to get the calculated thermodynamic properties of a stream also before an equilibrium calculation has been performed.
