Problem

A masonry wall has an area of

12\,\text{m}^2

and a thickness of

25\,\text{cm}

. The thermal conductivity of the masonry is

0.72\,\text{W}/(\text{m}\cdot\text{K})

. What temperature difference between the two sides of the wall will result in a steady conduction rate of

1.0\,\text{kW}

through the wall?
