(OP)
Can someone explain the advantages of purchasing NIST steam tables as opposed to going to their website?
Thanks

Using a Windows® interface, the STEAM database generates tables and plots of property values at specified conditions corresponding to saturation conditions, a fixed property value (isotherm, isobar, etc.), or individual values of two independent variables. Vapor-liquid, vapor-solid, and liquid-solid saturation calculations with either temperature or pressure specified are available. The user can specify which properties to display and the units in which to enter and display data. Additional features include an interactive on-line help system, the ability to plot calculated points and a wide variety of thermodynamic diagrams, and the capability to copy and paste data to and from other applications.
Source code: The FORTRAN subroutines and associated data files are provided for those wishing to access NIST-10 calculations from their own applications.
Excel spreadsheets: A sample spreadsheet is included that demonstrates how the DLL can be linked to Excel. Most properties that are available in the graphical interface can also be calculated in the spreadsheet.

I'm looking at transient flow in discharge piping downstream of a safety/relief valve.

I sometimes use website steam tables when I have relatively simple case to calculate in my work, for example check calculations. But for more in-depth analysis or simulation I use electronic steam tables for Mathcad or Excel.

My thoughts are that method of characteristics is the way to go. An over-simplification is an analysis of a shock tube open to the atmosphere. Perhaps this topic should be discussed on another forum.
