A,PPENDIX A FLUID PROPERTIES Th~ d~ensi@~less g.ro~ps used to correlate seat t·ransf'er data include i'0U.:i? fluid :properties; viscosity II ther.mal conductivity, heat eapaeitys amd &ensity. Literature values i'or these properties were used when they were available and the remainder 'i'lfere m.easured. The tem.pera~eaependent i'luid properties were expressed as a i'unetion oi' temperature. VISCOSITY .. I For Newtoniaa correlations the rheological behavior of' the fluids is expressed im terms of~ s the viscosity coefficient. Since this study includes n0n-Newtoni~ fluids for which the term viscosity is meaningless, the rheological behavior is described by the two constant, power law equation. The fluid properties which are measured are the flow behavior index, m" and the fluidconsistency index, K. The apparent viscosity for all the fluids used is thus given in teJ:"'l1ilS of :m. and K.· For use n-2 in. the dlmensionless groups K has the umits Ibo m sec. /i't. and n is dimensionless. NewtoniaE.
