steam_nbs

steam_nbs, a Fortran77 code which contains steam table functions devised by the Nation Bureau of Standards (NBS). This version of the code is (almost) unchanged from the original release. It can be useful when checking the revised Fortran90 version.

The code contains routines for computing various physical properties of water, related to temperature, pressure and density. Most of these routines use a standard set of SI units.

Minor changes have been made to the Fortran77 code, because of changes in the Fortran standard. In particular, in many places, the original code terminated a DO loop with a labeled statement which was neither an END DO nor a CONTINUE. These cases have been dealt with by inserting a following CONTINUE statement to which the label has been transferred. The code ought to compile now with no warnings or errors.
