Pr>1: Viscous sub-layer.
Pr>0.6: Buffer zone.
Pr<0.6: Turbulent core.
Pr>0.6: Buffer zone.
Pr<0.6: Turbulent core.

Conduction occurs in the buffer zone for a fluid flowing through a heated pipe only when the Prandtl number is greater than 0.6. The Prandtl number is a dimensionless quantity that characterizes the ratio of momentum diffusivity to thermal diffusivity.
A Prandtl number greater than 0.6 indicates that momentum diffusivity is greater than thermal diffusivity, which means that the fluid is more likely to transfer heat by conduction than by convection.
A Prandtl number greater than 0.6 indicates that momentum diffusivity is greater than thermal diffusivity, which means that the fluid is more likely to transfer heat by conduction than by convection.
