The analytical results for both geometries{ solid and dot-dashed curves) suggestt hat the dependenceo f the Nusselt number on Prandtl number is more complex than the simple power law appearingi n the empirical correlation. DeissIer [6] has shown a similar finding for the circular tube. The largest deviations between the empirical correlation and the theory appear in the midrange of Prandtl numbers( ~10). However, recentc are-ful measurementsb y Allen [?I for water flowing in a circular tube have demonstrated1 per cent agreement with the predictions of [l] at Pu =: 8.
