Unit in FluidDissipation correlation #502

Closed modelica-trac-importer closed 7 years ago

modelica-trac-importer commented 7 years ago

Reported by msielemann on 3 Mar 2011 10:31 UTC For the Gungor/Winterton correlation in HeatTransfer.StraightPipe.kc_twoPhase_overall_KC, the molar mass has to be supplied in g/mol. This is also done for the validation plots. Note that the List of Symbols in Bejan, which mentions kg/mol, thus seems to be erroneous.

In FluidDissipation, the unit attribute of SI.MolarMass prescribes kg/mol however. Preferably, the implementation of the correlation should therefore do a conversion from kg/mol to g/mol locally.
