A 50-cm diameter pipeline in the arctic carries hot oil at 30 degrees celsius and is exposed to a surrounding temperature of -20 degrees celsius. A special powder insulation 5 cm thick surrounds the pipe and has a thermal conductivity of 7 mW/(m x degees celsius). The convection heat-transfer coefficient on the outside of the pipe is 9 W/(m^2 x degrees celsius). Estimate the energy loss from the pipe per meter of length.
