Thermo-hydraulic Example Files

(non-relative references - MathCad 6.0 & 7.02a)

The following are a few MathCad worksheets 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:

** 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.

I've provided two examples. One for heat exchanger testing that is not well documented, and another for some simple pipe flow problems.

Faster, but still slow

These example worksheets make use of the following standardized worksheets:
