A hot steam pipe 10 cm in diameter is maintained at 200ºC and centered in a square mineral-fiber insulation 20 cm on a side. The outside surface temperature of the insulation is 35ºC. Calculate the heat lost by a 20-m length of pipe if the thermal conductivity of the insulation can be taken as 50 mW/m· ºC.
