Hi, I'm stuck on this derivation:
Derive an equation which shows that the temperature varies hyperbolically with the radius r for steadystate conduction of heat in a hollow sphere. I know the answer is: (TT1)/(T2T1) = (r2/(r2r1))(1(r1r)) But how do you get it? I also know that q = (T1T2)/((1/r11/r2)/(4pik)) Thanks
