CapeOpenMixtureProperty

CapeOpenMixtureProperty returns the values of a specified mixture property for a specified phase, at specified temperature, pressure and composition.

Syntax:

=CapeOpenMixtureProperty(packageName,propertyName,phaseName,T,P,composition,compositionBasis,propertyBasis,orientation,transposed,normalizeComposition)

Arguments:

packageName Name of the package.
propertyName The mixture property name, as defined by CAPE-OPEN. See the ribbon for which mixture properties are supported for the selected package. Mixture properties can be a scalar, or a vector with a value for each compound, or a square matrix the size of the number of compounds. Matrices are by default represnted as a vector. The unit of meaure can be obtained from CapeOpenUnitOfMeasure
phaseName The name of the phase. See the ribbon for which phases are defined by the selected package.
T The temperature, in K.
P The pressure, in Pa.
composition The composition, in mol/mol or kg/kg.
compositionBasis Optional. The basis for composition. Can be "mole" (default), or "mass".
propertyBasis Optional. The basis for the property. Can be "mole" (default), or "mass".
orientation Optional. Orientation can be 'auto'=0 (default), 'horizontal'=1, 'vertical'=2, 'matrix'=3 (if applicable).
transposed Optional. Can be "0" or "false" (default), or "1" or "true". Applies to matrix properties in all orientations.
normalizeComposition Optional. By default, the composition vector is normalized. Value can be "0" or "false", or "1" or "true" (default). Turning off composition normalization can be useful for composition perturbation, but note that the Property Package may internally normalizat composition.

Example:

=CapeOpenMixtureProperty("myPropertyPackage","enthalpy","vapor",298.15,101325,A3:A8)
