Reconsider Prob. 9-24. Using the EES (or other) 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.

Data from problem 24

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 highly polished surface A black oxidized surface. The plate midpoint temperature (T_L/2) has to be found iteratively. Begin the calculations by using a film temperature of 30°C.
