Configuration
5. If appropriate, enter the optional data for the Natural Gas Characterization Method that was selected
. Optional data for each method is listed in
6. Enter the
Nominal Operating Pressure
, then the
Nominal Operating Temperature
as the entry blanks
come available. Engineering Assistant will automatically fill in suggested operating ranges. Note that
these values may be edited by the user.
7. Select
Next
. This will open the
Fluid Properties
tab.
8. Proceed with the steps in
Ideal gas
The ideal gas option should be used when the fluid behavior can be modeled by the ideal gas law. This
option uses a modified version of the ideal gas law with a constant value of compressibility. The default
value for compressibility is 1.00 but it may be edited by the user. To use an ideal gas enter in the
operating pressure and temperature followed by either the density, specific gravity, or molecular weight.
1. Expand the
GAS
category.
2. Select the
Ideal Gas
option.
3. Enter the
Nominal Operating Pressure
and
Temperature Ranges
. Engineering Assistant will use these
ranges to identify the pressure and temperature values at which the fluid properties are required.
For the ideal gas being used the nominal density, specific gravity, or molecular weight must now be
entered using the drop-down menu. Once these are entered the other data entry fields, compressibility
and viscosity, are enabled as shown on
Figure 2-14. Fluid Selection Ideal Gas
4. Adjust the compressibility and viscosity to fit the ideal gas of the process.
5. Select
Next
to proceed to the
Fluid Properties
tab.
