SysML4Mathematica: Example 11 [B]: Total (qDotTot), sensible (qDotSen), and latent cooling (qDotLat) required for cooling air: Using Webel MPsy objects and SysML Activity Diagrams

In these Activity Diagrams we see how the previous problem can be setup using Webel MPsy objects, which encapsulate the lower level CoolProp calls. Together, they represent this Mathematica invocation:

ex11$cfm = 20000 unitCFM;

ex11$psy1 = newPsy[asDegF[90], $opt$psy$r -> 0.6];
 
ex11$psy2 = newPsy[asDegF[55], $opt$psy$r -> 1.0];

psy$dehumidify$qTotSenLat$table[
  ex11$psy1,
  ex11$psy2, 
  ex11$cfm, 
  $opt$psy$doShowAsIP -> True
]

Here unitCFM is a pre-built Mathematica Quantity[1.0, "Feet"^3/"Minutes"]:

The units utility function asDegF[magF_Real] creates a Quantity for °F.

The OpaqueBehavior +Q represents addition (Plus) of 2 Quantities in Mathematica, in this case to obtain 'qDotTotApprox' from 'qDotLatApprox' and 'qDotSenApprox'.

The OpaqueAction @asAssoc is a placeholder "analysis" function that represents constructing a Mathematica Association from 'qDotTot', 'qDotLatApprox', 'qDotSenApprox', and 'qDotTotApprox' with names as label keys.

When the output Association (represented as a SysML Block <||>) is displayed as a table the result is:
