Solution Impurities
WaterMassFlow / WaterQm	Calc	The mass flow of pure water (H2O(l)) in the stream.
LiquidMassFlow / LQm	Calc	The mass flow of liquids in the stream.
AqueousMassFlow / AqQm	Calc	The mass flow of aqueous species (including H2O(l)) in the stream.
SlurryVolFlow / SLQv	Calc	The volume flow of slurry (liquids + solids) in the stream.
TotalSuspendedSolids / TSS	Calc	The Total Suspended Solids (TSS) is the sum of all solids species, reported as a slurry (liquids + solids) concentration.
Liquid Impurity
Liquid.Impurity.MassFlow / Liq.Imp.Qm	Calc	The mass flow of all liquid species excluding water, in the stream.

H2O Properties

This section is used to display the included properties for: H2O Properties.

Data Section

Tag (Long/Short)	Input / Calc	Description/Calculated Variables / Options
H2O Properties This section will show water/steam entropy values. These will only be shown if the user has chosen to display the H2OProperties in the Plant Model - Views tab page or from the Include Properties dropdown list on the first page of the material Flow section. NOTES: If the project is using IF97 for the properties of steam and water then: The enthalpies will only be slightly different to the IF97 values shown here due to the slightly different reference temperature (0°C vs 0.01°C). The entropies will be different to the IF97 values by a fixed amount due to the different reference temperatures (0 Kelvin vs 0.01°C). The densities will be the same.
H2OProps (Water and Steam Properties) ...
Water.VapourT@P	Calc	Water vapour temperature (boiling point/saturation temperature) at the stream pressure.
Water.State	Calc	SysCAD checks the stream properties with the steam tables and displays if under the stream temperature and pressure, would all the H2O be liquid (water). If yes, it will display OK, if not it will display Invalid.
Water.Enthalpy / H	Calc	Water enthalpy (based on reference point of 0°C).
Water.IF97.Enthalpy / H	Calc	Water enthalpy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Water.Entropy / S	Calc	Water entropy (based on reference point of absolute zero (0K)).
Water.IF97.Entropy / S	Calc	Water entropy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Water.Density / Rho	Calc	Water density.
Water.IF97.Density / Rho	Calc	Water density calculated from IF97.
Steam.State	Calc	SysCAD checks the stream properties with the steam tables and displays: If under the current stream temperature and pressure, would all the H2O be vapour (steam). If yes, it will display OK, if not it will display Invalid.
Steam.Enthalpy / H	Calc	Steam enthalpy (based on reference point of 0°C).
Steam.IF97.Enthalpy / H	Calc	Steam enthalpy calculated from IF97 (based on reference point of triple point of water (0.01°C)).
Steam.Entropy / S	Calc	Steam entropy (based on reference point of absolute zero (0K)).
