Chapter 12, Problem 12.3P

The top surface of an $L=5-mm-thick$ anodized aluminum plate is irradiated with $\text{G=1000 }W/m^2$ while being simultaneously exposed to convection conditions characterized by $\text{h = 40 }W/m^2\cdot Kand{T}_{\infty }= {30}^{\circ }C$ . The bottom surface of the plate is insulated. For a plate temperature of 400 K as well as $\alpha =0.14\text{ and }\epsilon \text{ = 0}\text{.76}$ , determine the radiosity at the top plate sur-face, the net radiation heat flux at the top surface, and the rate at which the temperature of the plate is changing with time.
