Question
Consider a steam pipe of length L = 20 m, inner radius r₁ = 6 cm, outer radius r₂ = 8 cm,
and thermal conductivity k = 20 W/m-K, as shown in figure below. The inner and outer
surfaces of the pipe are maintained at average temperatures of T₁ = 150°C and T₂ = 60°C,
respectively. Using resistance model, determine the rate of heat loss from the steam through
the pipe. What is the temperature at the outer surface of the pipe? Pleass clearly show your
works.
