Steam at 120°c flows in an insulated 1% carbon steel pipe. the pipe inner radius is 10 cm and the outer radius is 11 cm. this is covered with a 3 cm thick layer of asbestos having a density of 577 kg/m3 . the outer asbestos surface is at 45°c. using carbon steel thermal conductivity, k=43 w/m-k and asbestos thermal conductivity k = 0.192 w/m-k, determine the heat transfer from the steam per meter of pipe length.
