A) 368.68W/m2
B) 3686.8 W/m2
C) 36.868 W/m2
D) 36868 W/m2
Correct Answer: A
Solution :
Net rate of energy transfer \[(E)=\sigma T_{1}^{4}-\sigma T_{2}^{4}\] \[=\sigma (T_{1}^{4}-T_{2}^{4})\] \[=5.672\times {{10}^{-8}}[{{(300)}^{4}}-{{(200)}^{4}}]\] \[=5.672\times {{10}^{-8}}\times (81-16)\times {{10}^{8}}\] \[=368.68W/{{m}^{2}}\]You need to login to perform this action.
