Answer:
<em>a. 14.5 W/</em><em></em>
<em>b. 58 W</em>
<em></em>
Explanation:
Thermal conductivity k = 0.029 W/m∙K
Temperature difference ΔT = 10 ℃
Thickness of sheet x = 20 mm = 0.02 m
area of sheet = 2m x 2m = 4
a. <em>heat flux q = k x (ΔT/x)</em>
q = 0.029 x (10/0.02)
q = 0.029 x 500 = <em>14.5 W/</em><em></em>
<em></em>
b. <em>Rate of heat transfer through the sheet Q = heat flux x area</em>
Q = 14.5 x 4 =<em> 58 W</em>
B. Always cut away from the body
