Problem

Two flat slabs each of area

0.50\,\text{m}^2

and thickness

0.02\,\text{m}

are made of materials X (

k = 0.20\,\text{W m}^{-1}\,\text{K}^{-1}

) and Y (

k = 0.05\,\text{W m}^{-1}\,\text{K}^{-1}

). If the temperature difference across each slab is

10\,\text{K}

, calculate the ratio of the heat current through slab X to that through slab Y.
