Computer Program for Calculating

Thermodynamic and Transport Properties of Fluids 
.
A computer code, GASP, has been developed to 
provide thermodynamic and transport properties of the 
following fluids: argon, carbon dioxide, carbon monoxide, 
fluorine, helium, methane, neon, nitrogen, oxygen, and 
parahydrogen. The equation of state and transport 
coefficients are updated and other fluids added as new 
material becomes available. 
GASP accepts any two of pressure, temperature or 
density as input conditions. In addition, pressure and 
either entropy or enthalpy are also allowable input 
variables. The properties available in any combination as 
output include temperature, density, pressure, entropy, 
enthalpy, specific heats (C r, Cv), expansion coefficient (C/C), sonic velocity, (aP/ap) T ,(aP/T) , viscosity, 
thermal conductivity and surface tension. A special 
technique is provided to estimate the thermal conduc-
tivity near the thermodynamic critical point. 
Properties are calculated at pressures from 0.1 to 400 
atmospheres (to 100 atmospheres for helium and 1000 
atmospheres for hydrogen). The temperatures range from 
near the triple point to 300 K (81 F) for neon, to 500 K 
(441°F) for carbon monoxide, oxygen and fluorine, to 
600 K (621°F) for methane and nitrogen, to 1000 K 
(1341°F) for argon and carbon dioxide, and to 2000 K 
(3141°F) for parahydrogen, and from 6 to 500 K(-449 to 
441 F) for helium (restricted use below 6 K (- 449'F)). 
The GASP package was developed to be used with heat 
transfer and fluid flow calculations, and as such has broad 
application. It appears to be particularly useful in the 
many applications of cryogenic fluids. Some of the 
problems associated with the liquefaction, storage and 
gassifIcation of liquefied natural gas and liquefied 
petroleum gas can also be studied using GASP. 
GASP was written for the engineer user who requires 
both accuracy and speed in calculating thermodynamic 
and transport properties.
Notes: 
1. This program is written in FORTRAN IV for use on 
the UNIVAC 1106 computer. 
2. It is also available for use on the IBM 7094/7044 DCS 
machine (reference LEW . 1 1629) and can be easily 
converted to a CDC machine with a FORTRAN IV/V 
compiler. 
3. The code is somewhat modular and can be used as a 
single package or disassembled for core storage limited 
problems. 
4. Inquiries concerning the program should be addressed
