thick-walled tube of stainless steel [18% Cr, 8% Ni, k = 19 W/m · ◦C] with 2-cm inner diameter (ID) and 4-cm outer diameter (OD) is covered with a 3-cm layer of asbestos insulation [k = 0.2 W/m · ◦C]. If the inside wall temperature of the pipe is maintained at 600◦C, calculate he heat loss per meter of length. Also calculate the tube–insulation interface temperature.
