Example: Steam flowing through a long, thin-walled pipe maintains the pipe wall at Uniform temperature of 500 k. the pipe is covered with an insulation blanket comprised of two different materials, A and B. The interface between the two materials may be assumed to have an infinite contact resistance and the entire out surface is exposed to air for which T = 300 k and h = 25 w/m2.k Sketch the thermal circuit of the system. What is the total heat losses from the pipe a? what are the outer surface temperature, Ts,2(A) Ts,2(B) Dr Mustafa Nasser
