Question

Two thin metallic spherical shells of radii r 1 and r 2 r 1 &#60; r 2 are placed with their centres coinciding. A material of thermal conductivity K is filled in the space between the shells. The inner shell is maintained at temperature &#952; 1 and the outer shell at temperature &#952; 2 &#952; 1 &#60; &#952; 2 . The rate at which heat flows radially through the material is :

Aicharya · Accepted Answer

Equivalent resistance ( R ) = r 2 - r 1 &#160; K 4 &#960; r 2 r 1 Thus, Heat flow = 4 &#960; K r 1 r 2 &#952; 2 - &#952; 1 r 2 - r 1
