A-7
16) Specific Heat K
Where,
K
i
= specific heat for component i
*C6/C7/C8 = 47/35/17
Constants are based on GPA2145-03, at base pressure 14.696psia, temperature 60
°
F
GPA2145-03 constants are used for HGC (version 3.0 or later) and HGM (version
4.60 or later).
GPA2145-00 constants are used for HGC (version earlier than 3.0) and HGM (version
earlier than 4.60).
