In chemical engineering, we often need property data from standard tables. Furthermore, from these tables, we may need intermediate values, which can be obtained by interpolation. If a certain table is frequently used, it is a good idea to create a Mathcad file containing these data and functions for property interpolation and use the file as a reference in other files that need the functions.
As an example, suppose that we want to create a reference file for calculating the properties of saturated water (Saturated water properties.xmcd). The following shows the content of this file:
Another Mathcad file can insert this file as a reference and all functions in that reference become available to use. The following shows the use of the above reference in a file:
