Find center temperature and maximum temperature in the wall.
Given that in problem
Radius of wire r = 0.001268m
Length of wire L= 0.9m
Average conductivity k = 22.5 W/m.K
Resistance R = 0.126 ohms
Current = 200A
Wall temperature Twall = 422.1K
Center Temperature and Maximum Temperature of a Wall are calculated from given data.
The solution is detailed and well presented.
