Heat and Mass Transfer

A cold storage wall consists of a $100\text{ mm}$ ($0.10\text{ m}$) thick layer of expanded polyurethane foam insulation ($k = 0.025\text{ W/(m}\cdot\text{K)}$). Calculate the conductive thermal resistance of the insulation layer per unit wall area in $\text{m}^2\cdot\text{K/W}$.
