A stainless steel plate 1.6cm thick rests on top of a hot plate, which is maintained at 250 degrees C. AIr flows over the top surface of the plate to provide a convective heat-transfer coefficient of h=50 W/m2 *K. The air temperature is maintained at 20 degrees C.

a) What is the heat flux through the stainless steel plate in W/m2 ?

b) What is the temperature at the top surface, T1 , of the stainless steel plate?

c) based on the analysis above, what can you conclude about the heat-transfer resistance offered by the hydrodynamic boundary layer?
