Question
A thick-walled tube of stainless steel with
thermal conductivity k = 19 W/m°C has inner
diameter of 10 em and outer diameter of 30
em is covered with 5 cm layer of asbestos
insulation with thermal conductivity k = 0.2
W/m°C. If the inside of the pipe and outside
of insulator temperature is maintained at
600°C and 106 °C respectively. Determine the
heat loss per meter length of pipe and the
tube-insulation interface temperature.
