XLThermo Documentation Help

Example spreadsheets

This page provides a collection of sample spreadsheets for XLThermo, that demonstrate how to use the software to perform common calculations in thermodynamics and heat transfer.

These examples demonstrate the software's capabilities and includes detailed calculations and usage scenarios to help you understand and leverage the features included in XLThermo.

Calculation of fluid properties

The most basic use of XLThermo is to calculate fluid properties. This example demonstrates how to use the software to calculate the properties of a fluid at a given flash specification, such as pressure and temperature (PT flash) or pressure and enthalpy (PH flash).

In addition, this example will show you how to use the built-in unit conversion functions to convert between different units of measurement.

Pressure drop over a valve

This example spreadsheet shows how to make a simple model of pressure drop over a valve. This is probably one of the most common processes in industry, so this should be very useful, but also shows how simple models can be implemented quickly using XLThermo.
