Calculate the thickness of the masonry wall having thermal conductivity of 0.75 W/mK if the heat transfer is to be 80% of the heat transfer through a composite structural wall having a thermal conductivity of 0.25 W/mK and a thickness of 100mm. Assume that both walls are subjected to same surface temperature.
