Examples and Templates

Running these examples from the web

Depending on the configuration of your web browser, you may be able to open and run these examples directly from the web if you have TPX installed locally. If you click on one of the links below, Excel will open the workbook in the browser. In this mode, the TPX command bar is hidden and the pop-up menu is disabled, but the command bar can be made visible by selecting View / Toolbars / TPX. As always, use Fix Links to fix the broken external links.

It is often easier, however, to download the file and then open it in Excel as usual.

Templates

TPX_Workbook.xlt

This workbook template comes with blank process representation plots (P-V, P-H, H-S, T-V, T-S), one per sheet. A sheet labeled "Substance" is also provided, and if you enter the substance name on this sheet in the specified cell, the vapor domes on all plots will be recomputed. If you change units they will be also.

Go to a blank page and solve your problem, then use the right mouse button to quickly produce all of the above process representations in one step.

If you don't want to change the units and substance, you can go to sheet "Data Sheet" and using "Paste Special" convert all formulas to numbers. This will keep the vapor domes fixed, and not waste time recalculating them. In this way, you can create your own templates for particular substances in your favorite unit system.

Example Worksheets

List.xls

A simple list of properties with units. If you are new to TPX, take a look at this simple example to see how changing the substance or units affects the results.

Nozzle.xls

Isentropic, equilibrium flow of a condensible vapor. Test your TPX abilities and see if you can reproduce the plot given of liquid mass fraction vs. pressure ratio.

Clapyron.xls

A numerical test using the Clapyron equation to determine whether the properties computed by TPX (and their derivatives) are thermodynamically consistent.

Rankine.xls

An ideal Rankine cycle with superheat.
