What Is The Effect Of The Prandtl Number Of A Fluid On The Relative T

1.	What Is The Effect Of The Prandtl Number Of A Fluid On The Relative Thicknesses Of Velocity And Temperature Boundary Layers When The Fluid Flow Is Parallel To A Flat Plate?
Answer» For LAMINAR flow, the ratio of the boundary layer THICKNESS d to that of the thermal boundary layer, dt, is given by: d/dt u Prn. The HIGHER the Prandtl number, the larger is the ratio. For laminar flow, the ratio of the boundary layer thickness d to that of the thermal boundary layer, dt, is given by: d/dt u Prn. The higher the Prandtl number, the larger is the ratio.

Answer»

For LAMINAR flow, the ratio of the boundary layer THICKNESS d to that of the thermal boundary layer, dt, is given by:

d/dt u Prn.

The HIGHER the Prandtl number, the larger is the ratio.

For laminar flow, the ratio of the boundary layer thickness d to that of the thermal boundary layer, dt, is given by:

d/dt u Prn.

The higher the Prandtl number, the larger is the ratio.
