STEAM_INTERACT
Query the NBS Steam Tables

STEAM_INTERACT is a FORTRAN90 program which allows the user to query the NBS steam tables.

The user can specify temperature and pressure, or temperature and density, and the program will return the computed values of a variety of quantities.

Most of these routines use a standard set of SI units. The original routines were written in FORTRAN77. This FORTRAN90 version has been extensively rewritten, with some additional routines for computing quantities such as the viscosity, thermal conductivity, and the Prandtl number.
