A) 200 \[W{{m}^{-}}^{2}\]
B) 65 \[W{{m}^{-}}^{2}\]
C) 120 \[W{{m}^{-}}^{2}\]
D) 90 \[W{{m}^{-}}^{2}\]
Correct Answer: D
Solution :
Heat current \[H\,\,=\,\,\frac{kA\Delta T}{L}\] Heat flux \[=\,\frac{H}{A}\,\,=\,\frac{k\,\Delta \,T}{L}\,=\,\frac{0.1(900)}{1}\] \[=\text{ }90\text{ }W{{m}^{-}}^{2}\]You need to login to perform this action.
