A stainless steel pipe ( k 15 W/[m °C]) with a 2.5 cm inner diameter and 5 cm outer diameter is being used to convey high-pressure steam. The pipe is covered with a 5 cm layer of insulation ( k 0.18W/[m °C]). The inside steel pipe surface temperature is 300°C, and the outside insulation surface temperature is 90°C. a. Determine the rate of heat transfer per meter length of the pipe. b. The insulation selected for the purpose has a melting temperature of 220°C. Should you be concerned about the integrity of the insulation for the listed conditions?
