MathCad Files

The following are a few MathCad files that are present on this website. These are intended to show the benefits of standardized reference worksheets. Specifically, these demonstrate standardized, reusable, worksheets for thermo-hydraulic work. They include worksheets for water properties, heat exchanger characteristics, and pipe flow. These standardized reference worksheets can be included in other worksheets and thus eliminate the need to rebuild custom sets of equations for these subject areas. Two different sets of files are available:

MathCad Version^*	Description
6.x or 7.02a	Uses hard coded URLs for the reference documents. These documents only work from this website. The link to the left opens an HTML document from which you will be able to open the relevant example files.
8.02a	Uses relative reference for the reference documents. These documents can be downloaded and used on any local hard drive, LAN, or internet site (but only with permission). The link to the left opens a MathCad worksheet from which you will be able to open the relevant examples files.

Note that the non-patched version of MathCad 7.0 and 8.0 will not work.

** WARNING **

There is no warranty or assurance of accuracy for any of these worksheets (e.g., certain parameters for water have been shown to have large inaccuracy at certain points in the curves). I have tested for my own uses, but you will need to assure they meet your individual project needs for modeling correctness and accuracy.

^*NOTES:

MathCad is a Mathsoft product.
Other example worksheets are available on this site. The directory listing of the MathCad files lists all the worksheets on this web.
MathCad 6.x: These worksheets should work in MathCad 6.x. These worksheets were originally created in MathCad 6.x. MathCad 6.x did not support the addition of Internet based references via its editor, but they could be added manually by editing the underlying text of the worksheet. I haven't opened these in a while in 6.0, but it should still work. I have never tried these with the Macintosh version of 6.x.
MathCad 7.x: These worksheets will work in MathCad 7.02a, but not in earlier versions of 7.x. The patches to update earlier versions are available at: http://www.mathsoft.com/patch.htm.
MathCad 8.x: These worksheets will work in MathCad 8.02a, but not in earlier versions of 8.x. The patches to update earlier versions are available at: http://www.mathsoft.com/patch.htm. The specific problems are:

MathCad 8.0 has a bug where the ORIGIN value is not recognized correctly by certain functions and features. Updating to MathCad 8.01a or 8.02a will fix this problem.
MathCad 8.01a explicitly allows the inclusion of Internet based reference worksheets. However, it does not properly include the functions from the Internet reference worksheets. Updating to MathCad 8.02a will fix this problem.
A "neat" feature of MathCad 8.x is that allows users to download and use these files from their local drive or network without modification if they were built with 8.x's "relative references". While this is a great feature that allows you to finally share reference worksheets between sites, when the documents are placed on an website they will not open via a web browser. MathCad looks for the reference worksheets in the web browser's temporary directory. On this site, I've provided a MathCad worksheet that provides the appropriate links to open the example files. It would be much better if I could use and HTML document for these links. I am looking forward to when they fix this relative reference problem. Once the fix is in, I will change the MathCad 8.x site over to a HTML master document that will improve your ability to navigate and download files from the site.
