The equation has the following form:

TempDep Corr 91

You must use at least 1 coefficient with this correlation.

You can use up to 10 coefficients with this correlation.

You can use any temperature unit of measure (UOM) when you input data for this correlation.

To avoid infinite values for the property calculation, the property value has a maximum limit of 106 and a minimum limit of -106.

Usage

This correlation currently applies only to liquid density. You cannot select it for any of the temperature-dependent properties currently available in AVEVA Thermodynamic Data Manager. However, you can select this correlation and change the coefficient values in the Component Data section of the Fluid Editor.

We recommend that you use this correlation for the liquid density of ions.
