Reconsider Prob. 20€“22. Using an appropriate software, evaluate the effect of the uniform surface heat flux on the plate midpoint temperature for

(a) The highly polished surface

(b) The black oxidized surface. By varying the surface heat flux from 500 to 1500 W/m², plot the plate midpoint temperature as a function of the surface heat flux.

Reconsider Prob. 20€“22.

A 0.5-m-long thin vertical copper plate is subjected to a uniform heat flux of 1000 W/m² on one side, while the other side is exposed to air at 5°C. Determine the plate midpoint temperature for

(a) A highly polished surface

(b) A black oxidized surface.
