Template:PHREEQC OpMode

OpMode Temperature The target variable is the Temperature of the final solution. | FeedT || The target variable is the Temperature of the feed solution. |- | Enthalpy || Only available if Model = Reactor. The target variable is the Enthalpy of the final solution. |- PhaseFormation The target variable is the amount of a particular phase present in the final solution. SpeciesFormation The target variable is the amount of a particular species present in the final solution. |- | TemperatureReqd / T_Reqd || Input || Only visible if OpMode = Temperature. The user specified target temperature for the final solution. |- | dEnth.Reqd / dH.Reqd || Input || Only visible if OpMode = Enthalpy. The user specified target duty. |- | CalcEnthalpy || Tickbox|| Visible when OpMode ≠ Enthalpy. If the calculation requires a heat balance, then this option should be selected. If heat balance is not required, untick this option to save on computation time.
Note: unticking this option will also remove the enthalpy display from the Input and Output tabs. |- The following fields are only visible if OpMode = PhaseFormation SelPhase... Filter Input Filter by "contained" string. Allows user to optionally shorten the Phase Selection list (Phase) by entering in some letters from the desired phase. Phase List The user can select one phase from the list of all phases in the PHREEQC database. The list will not show all phases if user has entered some letters in the Filter field above. MoleBasis Tickbox Selecting this tickbox allows the user to specify the target mole flow. If this is not selected, then mass flow is used. Phase.MassFlowReqd / Phase.QmReqd Input Only visible if MoleBasis = unticked. The user specified mass flow of the chosen phase that is to be formed. Phase.MoleFlowReqd / Phase.QMlReqd Input Only visible if MoleBasis = ticked. The user specified moles of the chosen phase that is to be formed. The following fields are only visible if OpMode = SpeciesFormation PhaseFilter.... Filter Input Filter by "contained" string. Allows user to optionally shorten the Phase Selection list (Phase) by entering in some letters from the desired phase. Phase List The user can select one phase from the list of all phases in the PHREEQC database. The list will not show all phases if user has entered some letters in the Filter field above. SpFilter.... Filter Input Filter by "contained" string. Allows user to optionally shorten the Species Selection list (Species) by entering in some letters from the desired species. Species List The user can select one species from the list of all species in the PHREEQC database. The list will be limited to those in the selected phase (Phase) and will not show all species if user has entered some letters in the Filter field above. MoleBasis Tickbox Selecting this tickbox allows the user to specify the target mole flow. If this is not selected, then mass flow is used. Sp.MassFlowReqd / Sp.QmReqd Input Only visible if MoleBasis = unticked. The user specified mass flow of the chosen phase/species that is to be formed. Sp.MoleFlowReqd / Sp.QMlReqd Input Only visible if MoleBasis = ticked. The user specified moles of the chosen phase/species that is to be formed.
