The thickness of thermal and hydrodynamic boundary layer is equal if Prandtl number is

Answer & Solution
Correct Answer: Option A
If the Prandtl number (Pr) is 1, the two boundary layers (hydrodynamic and thermal) are the same thickness.
If the Pr > 1, the thermal boundary layer is thinner than the velocity boundary layer.
