The Fluid Properties Database allows you to calculate the properties of the chosen material according to its pressure and temperature.

The calculated properties are:

For Liquid

For Gas

Density and Specific Gravity

Density and Specific Gravity

Vapor pressure

Compressibility

Viscosity

Viscosity

Liquid Heat Capacity

Specific Heat Ratio

This option is not available for materials where the Fluid state is Solid/Powder or N/A or other nor for 2-phase Fluid phase.

  1. Open the process data sheet.

  2. In the Process Data window, from the Fluid name source list, select Database.

  3. From the Fluid list, select the fluid.

  4. In the PROPERTIES section, enter the appropriate pressure and temperature values.

  • Smart Instrumentation calculates and displays changed values.

  • Smart Instrumentation uses the AIChE databank to calculate physical properties; therefore, your values must comply with the AIChE temperature limits. AIChE data does not provide accurate calculation of density, compressibility, and specific gravity for ethylene and propylene at critical pressure and temperature. For this reason, the software implements the procedure described in William C. Reynolds, SI, Department of Mechanical Engineering, Stanford University.

  • To calculate liquid density, on the Options menu, select Calculate Liquid Compressibility.

  • To calculate the steam properties, on the Options menu, select Saturated Steam.
