Question Answered step-by-step A pipe of outer diameter 50mm. maintained at 1100K. is covered with… A pipe of outer diameter50mm. maintained at 1100K. is covered with 50mm ofinsulation of thermal conductivity 0.17 watts per meter per Kelvin. Would it befeasible to use a magnesia insulation which will not stand temperatures above615K and has a thermal conductivity of 0.09 watts per meter per Kelvin for anadditional layer thick enough to reduce the outer surface temperature to 370K insurroundings at 280K? Take the surface coefficient of heat transfer by radiationand convection as 10 watts per sq. meter per Kelvin.(Hint: Determine thetemperature at the interface of the pipe and insulation to compare with the giventhreshold).
