These properties are related to the saturation temperature and pressure of solution. These fields are only visible if the Additional Properties option for Saturation values is selected in the Plant Model - Views tab page or from the [[Material_{{{type}}}_Section#Qo_.28Qxxxx.29_Tab_Page|Include Properties]] dropdown list on the first page of the material {{{type}}} section. |- |font style="background: #ebebeb" colspan="3" | Saturation... |- |Component || List || Any component that has the correct Vp Equations defined in the species database maybe selected here. See VLE sub section for more information. |- |VapourFrac / Vf || font style="background: #ebebeb" |Calc || Only available in Build 137 or later. Displays the vapour mass fraction. |- |TotalP || font style="background: #ebebeb" |Calc || Displays the total pressure. |- |PartialP || font style="background: #ebebeb" |Calc || Displays the partial pressure based on the component selected. |- |[email protected] || font style="background: #ebebeb" |Calc || Saturated pressure at the mixture temperature. |- |[email protected] || font style="background: #ebebeb" |Calc || Saturated temperature at the mixture's partial pressure. Will be NAN (displayed as *) when no partial pressure. |- |[email protected] || font style="background: #ebebeb" |Calc || Saturated temperature at the mixture pressure. |- |[email protected] || font style="background: #ebebeb" |Calc || Displays the Saturation Temperature at pressure based on pure water. This is used to calculate the Boiling point elevation. (Please see Water and Steam Properties for further information on this calculation) |- |valign="top"|BPE || font style="background: #ebebeb" valign="top" |Calc ||

Note: User can change the BPE value limits in the Plant Model - species tab. |- |Temperature / T || font style="background: #ebebeb" |Calc || Temperature of the {{{UnitOp}}}. |- |[email protected] || font style="background: #ebebeb" |Calc || Super Heat at the mixture's partial pressure ([email protected]). Will be NAN (displayed as *) when no partial pressure. |- |[email protected] || font style="background: #ebebeb" |Calc || Super Heat at the mixture's pressure ([email protected]). |- |[email protected] || font style="background: #ebebeb" |Calc || Only available in Build 137 or later. The amount of Subcooling at the mixture's pressure ([email protected]). |- |LatHtVap || font style="background: #ebebeb" | Calc || The Latent heat of vaporisation of the listed component at the temperature and partial pressure of the vaporizing species at the local conditions. The latent heat is the difference in enthalpy between the vapour phase and the liquid phase of the species. This is calculated as Enthalpy(VapourPhase at local Temperature and Partial Pressure) - Enthalpy(Liquid Phase at T and Total Pressure). This is the enthalpy difference used in energy calculations. NB unless the partial pressure of the vaporizing species is equal to the saturation pressure, the latent heat may not have exactly the same value as for saturation conditions since the vapor phase enthalpy depends on its partial pressure. |- |[email protected] || font style="background: #ebebeb" | Calc || The Latent heat of vaporisation of the listed component at the temperature and saturation pressure of the vaporizing species corresponding to the local temperature. The latent heat is the difference in enthalpy between the vapour phase and the liquid phase of the species. This is calculated as Enthalpy(VapourPhase at Temperature, T and saturation pressure for that T, PSat(T)) - Enthalpy(Liquid Phase at T and Total Pressure). This is the latent heat that would be found in saturation tables for a given temperature. |- |RelHumidity || font style="background: #ebebeb" |Calc || The relative humidity of the {{{UnitOp}}}. This is only useful if the {{{UnitOp}}} contains gases, such as O2, N2, Air, etc.
Relative Humidity = Partial Pressure of the Saturation Component (usually H2O) / Saturation Pressure of the Saturation Component at Stream Temperature * 100
