Thickness of thermal boundary layer is more compared to that of hydrodynamic boundary layer, when the value of Prandtl number is
A)1
B)< 1
C)> 1
D)> 5

Quizplus · Accepted Answer

When the Prandtl number is less than 1, the thermal diffusivity is greater than the momentum diffusivity, leading to a thicker thermal boundary layer compared to the hydrodynamic boundary layer.
