Abstract
A universal finite Nusselt number is found for laminar slip flow heat trans fer at the entrance of a conduit. The Nusselt number expression is valid fo r both isothermal and isoflux thermal boundary conditions and for any condu it geometry. The value of the entrance Nusselt number is found to be depend ent on two nondimensional parameters that include effects of rarefaction, f luid properties, and the fluid/wall interaction.
