a three layered composite pipe with an inside diameter of 1cm has an internal surface temperature of 120. the first layer from the inside to the outside, is 2cm thick with a thermal conductivity of 15w/m the second layer is 3cm thick with a thermal conductivity of 0.04w/m and the third layer is 1cm thick and has a thermal conductivity of 164w/m. the outside surface temperature of the composite pipe is 60.a. determine the rate of heat transfer through the pipe under steady-state conditionsb. can you suggest an approach that will allow you to qiuckly make an estimate for this problem
