Density Correction | ||
H2O(l).State | Data | This will be OK if all of the species with density correction functions in the {{{UnitOp}}} conditions are within their mass fraction limits. Any species that has exceeded it's mass fraction limit will be shown in this field. For example, if the user has a density correction function for NiSO4(aq) that is valid up to a mass fraction of 10% NiSO4 and the stream contains 15% NiSO4(aq), this field will contain: Limit:NiSO4(aq). |
H2O(l).Rho | Calc | The density of pure water at the temperature and pressure of the {{{UnitOp}}}. |
H2O(l).CorrFactor | Calc | The calculated density correction factor using all the correction factors of aqueous species in the {{{UnitOp}}} for which density correction factors have been defined. Please see Density Correction Function. |
H2O(l).AppRho | Calc | The calculated density of the liquor with only water and the components that have density correction functions.
Note: This value may be lower or higher than the actual liquid density if there are other liquid components in the {{{UnitOp}}} that do not have density correction functions. |
If the Additional Density Correction option is selected in the Plant Model - Species 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, then the following fields will also be shown: | ||
H2O(l).AppRho25 | Calc | The calculated density of the liquor with only water and the components that have density correction functions, at 25°C. |
Calc | The calculated mass of the liquor with only water and the components that have density correction functions. | |
