Q1/ A thick wall consists two layers of Gypsum, insulation and brick as shown in
figure below. The ambient temperature is 20 °C and heat transfer coefficient is 5
W/m2. K in the left side. The surface temperature of right side is 45 °C. find the
heat losses per meter length. What will happen if the insulation's thickness
* .increases by 25%
Gypsum k = 0.04W/m. K
T = 45 °C
h=5 W/m'. K
T. = 20 °C
