In Fig. 18-42a, two identical rectangularrodsof metal are welded end to end, with a temperatureofT1 = 0°C on the left side and a temperatureofT2 = 100°C on the right side. In 2 min,10 J isconducted at a constant rate from the right side to theleft side.How much time (in minutes) would be required to conduct10 J if therods were welded side to side as inFig.18-42b?
I looked at a similar solution and had issues following thepersonswork. I just dont understand how with the two equations somanyunknowns can be solved out.
