getFeedProp

getFeedProp is used to obtain thermodynamic and physical properties from feed ports.

Syntax

value=getFeedProp(feedIndex,propName)

Arguments

feedIndex
Integer; the index of the feed to obtain the property from. The index must be between one and the number of feeds - inclusive.

propname
String; the property to obtain. Valid properties are:

Property	Description	Unit of measure
temperature	Temperature	K
pressure	Pressure	Pa
flow	Component flows, one value for each chemical compound	mol / s
totalFlow	Total flow	mol / s
fraction	Overall mole fraction	-
enthalpy	Default enthalpy	J / mol
enthalpyF	Enthalpy - including formation terms	J / mol
enthalpyNF	Enthalpy - not including formation terms	J / mol
entropy	Default entropy	J / mol / K
entropyF	Entropy - including formation terms	J / mol / K
entropyNF	Entropy - not including formation terms	J / mol / K
internalEnergy	Energy	J / mol
volume	Specific volume	m3 / mol

Not all of these properties may be supported by the underlying thermo system. The default enthalpy term will generally be available. The enthalpyF property may not be available, but if it is it is the preferred enthalpy for systems that include chemical reactions.

Returns

value
The value of the requested property. The unit of measure of the value is indicated in the above table
