Suppose a 3 in schedule 80 steel pipe is covered with 1 in of an insulation having k = 60 mW/moC and the outside of the insulation is exposed to an environment having h = 10 W/m2oC and Tf = 20oC. The temperature of the inside of the pipe is 250oC. For unit length of the pipe calculate (a) the overall thermal resistance and (b) the heat loss (in Watts).
