Temperature/Pressure Dependent Pressure Series Dialog
Applicability: Cranium, Synapse (core versions 0315+)

The Pressure Series Dialog is used by the Temperature/Pressure Estimates Dialog to generate a series of state variables consisting of a fixed temperature value and pressures varying between specified limits.

Dialog Controls

The Pressure Series dialog provides controls for specifying a fixed temperature and a range of pressure values.

1
Constant Temperature Control: enables you to enter a temperature value that will be assigned to each generated set of state variables.
2
Starting Pressure Control: enables you to enter the lower limit of the generated pressures.
3
Limits Buttons: pressing either button activates the Property Limits Dialog. This dialog enables you to select from a list of common pressure limits, e.g., triple point pressure, critical pressure, or atmospheric pressure. (See below for additional documentation.)
4
Limit Type Control: enables you to select if pressure values will be generated between a starting and ending limit or will be incremented by a specified amount. See below for details.
5
Limit Amount Control: enables you to enter either the upper pressure limit or the increment used to generate pressure values. See below for details.
6
Number of Rows Control: displays the number of table rows into which the series values will be pasted. This number is initially equal to number of table rows selected in the estimates dialog.
7
Increment/Decrement Control: enables you to increment or decrement the number of rows into which the series values will be pasted.
8
Display Control: if you select Ending Pressure for the limit type, then this control displays the calculated increment between pressure values. If you select Pressure Increment as the limit type, then this control displays the calculated ending value.
Pressure Limits Dialog

Pressing either of the Pressure Series Dialog's Limits buttons activates the Property Limits dialog.

The dialog enables you to choose from common pressure limits, i.e., triple point pressure, critical pressure, and atmospheric pressure. A physical property based pressure limit is only listed if there is a data value for that property.

Selecting a pressure limit and pressing the Select button inserts that value into the correpsonding pressure control in the Series dialog.

Ending Pressure or Pressure Increment

Pressure values can be generated between two limits, the Starting Pressure and the Ending Pressure, or by repeatedly incrementing the starting pressure by a specified amount. The dialog's Limit Type control specifies which type of series to generate.

Assuming the number of rows equals 6, the entries to the right would generate pressures of: 50, 70, 90, 110, 130, and 150 kPa.

Assuming the number of rows equals 6, the entries to the right would generate pressures of: 50, 60, 70, 80, 90, and 100 kPa.
