Consider a long cylindrical tube of inner and outer radii ri and ro, respectively, and length L and thermal conductivity k. Its inner and outer surfaces are maintained at Ti and To respectively (Ti > To). Assuming one-dimensional steady-state heat conduction in the radial direction, the thermal resistance in the wall of the tube is
A
(1/2πkL) ln(ro/ri)
B
L/(2πkri)
C
(1/2πkL) ln(ri/ro)
D
(1/4πkL) ln(ri/ro)

Correct : a
