Consider a plane wall of thickness '2L' in which there is uniform heat generation of q per unit volume. The surfaces are maintained at temperatures T1 and T2 on the left and right sides respectively. Thermal conductivity (k) is constant and the origin is placed at midpoint of the plane wall.
1
the maximum temperature lies exactly at the mid plane
2
the maximum temperature lies at a distance of \(\frac{k\left( {{T}_{1}}-{{T}_{2}} \right)}{2qL}\) from the mid plane
3
the maximum temperature lies at a distance of \(\frac{k\left( {{T}_{1}}-{{T}_{2}} \right)}{qL}\) from the mid plane
4
the maximum temperature lies at a distance of \(\frac {2qL}{k({{T}_{1}}-{{T}_{2}})}\) from the mid plane
