4. The outer facing of a room is constructed from 0.75 m thick brick, 25 cm of mortar, 12 cm of limestone (k=0.186 W/mK) and 0.5 m of plaster (0.096 W/mK). Thermal conductivities of mortar and brick are both 0.52 W/mK. Assume that the heat transfer coefficients on the inside (plaster side) and outside (brick side) surfaces of the wall to be 8 and 24 W/(m^2 K), respectively. Calculate the overall coefficient of heat transfer (W/(m^2 K).. Show your solution

4. The outer facing of a room is
constructed from 0.75 m thick brick,
25 cm of mortar, 12 cm of limestone
(k=0.186 W/mK) and 0.5 m of plaster
(0.096 W/mK). Thermal conductivities
of mortar and brick are both 0.52
W/mK. Assume that the heat transfer
coefficients on the inside (plaster side)
and outside (brick side) surfaces of
the wall to be 8 and 24 W/(m^2 K),
respectively. Calculate the overall
coefficient of heat transfer (W/(m^2 K).
