A 50-cm-diameter pipeline in the Arctic carries hot oil where the outer surface is maintained at 30°C and is exposed to a surrounding temperature of -15°C. Aspecial powder insulation 5 cm thick surrounds the pipe and has a thermal conductivity of 7mW/m°C. The convection heat-transfer coefficient on the outside of the pipe is 9 W/m2°C. Estimate the energy loss from the pipe per meter of length.
