capeOverallProperty performs a thermodynamic equilibrium calculation at specified conditions, and calculates an overall property by summation over the phases at equilibrium. As overall properties are generally extensive, capeOverallProperty generally will return a scalar value.
For the unit of measure of an overall property, use capeSinglePhasePropertyUnit.
Feed streams are already flashed. So instead of using capeOverallProperty at feed conditions, use capeOverallFeedProperty.
=capeOverallProperty(propName, specProp1, specValue1, specProp2, specValue2, moleFraction)
|propName||Name of the property. For a list of available overall properties, click the Overall Properties button on the control sheet. Derivatives for overall properties are not supported.|
|specProp1||Property for first flash specification. For a list of valid flash specifications, click the Flash Specifications button on the control sheet. In addition to all overall properties, properties Pressure and Temperature can be used as flash specification, as well as special property vaporfraction (molar phase fraction of the vapor phase).|
|specValue1||Value of the first flash specification property.|
|specProp2||Property for second flash specification.|
|specValue2||Value of the second flash specification property.|
|moleFractions||Overall composition for which to calculate the equilibrium; number of values must correspond to the number of compounds. Composition must be normalized.|
