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:
qDotTot | -1.546632642093384 10^6 Btu/hr |
qDotLatApprox | -805733.3295464187 Btu/hr |
qDotSenApprox | -755327.385263709 Btu/hr |
qDotTotApprox | -1.5610607148101279 10^6 Btu/hr |
