: Online Property Calculation

The online-calculation service on this website was started recently, both with the aim to test the potential of this kind of web tool and to retrieve some user feedback.

It is currently limited to five common temperature dependent properties and the components that come with the free Explorer Edition. For the future we are considering to optimize and extend this service to make it more applicable to practical engineering problems.

As we will not be able to extend the scope of components on a cost-free basis, we are evaluating ways to provide this extended service on a pre-paid basis for registered customers.

The current implementation of the online-calculation presents separate pages for each of the following properties in the menu on the left:

• Vapor pressure calculation by the Antoine equation

• Liquid density calculation by the DIPPR 105 equation

• Liquid dynamic viscosity calculation by the Vogel equation

• Surface tension calculation by the DIPPR 106 equation

• Heat of Vaporization calculation by the PPDS12 equation

The parameters for the equations have been fitted to experimental data from the Dortmund Data Bank and are not those delivered by DIPPR or PPDS.

Please refer to the Pure Component Property Regression Tutorial for further information about the equation forms.
