Question
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
Wim2. 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
5 cm
Insulation
k=0.04W/m. K
Brick
k=0.69 W/m. K
