For flow of fluid over a heated plate, the following fluid properties are known:
Viscosity = 0.001 Pa.s, Sp. Heat at constant pressure = 1 kJ/kg-K, thermal conductivity = 1W/mK.
The hydrodynamic boundary layer thickness at a specified location on the plate if 1 mm, the thermal boundary layer thickness at the same location is
1
0.001 mm
2
0.01 mm
3
1 mm
4
10 mm
