An asbestos pad is square in cross section, measuring 5 cm on a side at its small end and it increases linearly to 10 cm on a side at the large end. The pad is 15 cm high.

A. If the small end is held at 600 K and the large end at 300 K, what heat-flow rate will be obtained if the four sides are insulated? Assume one-dimensional heat conduction. The thermal conductivity of asbestos is 0.173 W/m*K. Report answer in units of W.

B. What is the heat flow rate if the larger cross section was at 600 K and the smaller end at 300 K? Report answer in units of W.
