Question

Heat is generated uniformly in a long solid cylindrical rod (diameter =10 mm= 10\text{ mm}) at the rate of 4×107 W/m34 \times 10^7\text{ W}/\text{m}^3. The thermal conductivity of the rod material is 25 W/m⋅K25\text{ W}/\text{m}\cdot\text{K}. Under steady state conditions, the temperature difference between the centre and the surface of the rod is ________ ∘C^\circ\text{C}.
