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?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
