Question

In laminar flow over a flat plate for air, (a) the thermal boundary layer and hydrodynamic boundary layers are of equal thickness (b) the thermal boundary layer is thicker if the prandtl number is greater than one (c) the thermal boundary layer is thicker if the prandtl number is less than one (d) the thermal boundary layer is always thinner in the laminar region.

Answer 1

answers of option d

thermal boundary layer is always thinner in the laminar region

Answer 2

In laminar flow over a plate of air (d) the thermal boundary layer is always thinner in the laminar region

Explanation:

• In fluid dynamics, laminar flow is characterized by fluid particles following smooth paths in layers
• it is designed to prevent combination of semiconductor wafers, biological samples, any particle sensitive materials.
• due to collection of spores the cabinet is made of stainless steel with no gaps or joint
