A transport and thermodynamic properties package for simulation and design

Transport and thermodynamic properties such as viscosity, thermal conductivity, enthalpy, etc., are frequently needed in chemical process computations. A computer program was written which calculates these and many other related properties rapidly and efficiently. The system consists of an executor or main subroutine called ROADMP plus 36 subroutines. ROADMP decides what subroutines have to be used to calculate a given property from input data provided by the user. All the subroutines, except ROADMP, consist of small programs that use physical property correlations taken from the literature. Extensive tests and error checks were made and are included, where possible, in the system. The entire program consists of 3,200 FORTRAN statements and occupies 11K words of memory.
