A very long, 10 mm diameter cooper rod (k= 370w/ (m k)) is exposed to an environment at 200 c. the base temperature of the rod is maintained at 1200c. the heat transfer coefficient between the rod and the surrounding air is 10 w/m^2 k. Determine the heat transfer rate for finite lengths, 0.02, 0.04,0.08,0.2,0.4,0.8,1 and 10 meters assuming heat loss at the end.
