A thick-walled tube of stainless steel (A) having a k= 21.63 W/m · K with dimensions of 0.0254 m ID and 0.0508 m OD is covered with a 0.0254-m layer of asbestos (B) insulation, k = 0.2423 W/m · K. The inside wall temper- ature of the pipe is 811 K and the outside surface of the insulation is at 310.8 K. For a 0.305-m length of pipe, calculate the heat loss and also the temperature at the interface between the metal and the insulation.

Question
A thick-walled tube of stainless steel (A) having a k = 21.63 W/m K with
dimensions of 0.0254 m ID and 0.0508 m OD is covered with a 0.0254-m
layer of asbestos (B) insulation, k = 0.2423 W/m · K. The inside wall temper-
ature of the pipe is 811 K and the outside surface of the insulation is at 310.8
K. For a 0.305-m length of pipe, calculate the heat loss and also the
temperature at the interface between the metal and the insulation.
