Consider a long pipe of inner radius r1, outer radius r2, and thermal conductivity k. The outer surface of the pipe is subjected to convection to a medium at T? with a heat transfer coefficient of h, but the direction of heat transfer is not known. Express the convection boundary condition on the outer surface of the pipe.
What will be an ideal response?
A long pipe of inner radius r1, outer radius r2, and thermal conductivity k is considered. The outer surface of the pipe is subjected to convection to a medium at with a heat transfer coefficient of h. Assuming steady one-dimensional conduction in the radial direction, the convection boundary condition on the outer surface of the pipe can be expressed as
