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:
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.
|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.
- 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
