Question
1. An epoxy board (k=.4 W/m.k & thickness of .1 cm) is impregnated with copper cylinders with k=400 W/m.K to enhance heat transfer. The board is 6 cm by 6 cm and the copper cylinders occupy 10% of this area. The space on the backside of the board is a vacuum that is enclosed by a surface at 300 K. the heat transfer from the front side of the board is uniformly 100 W/m^2 thru the board. What is the temperature of the back side of the board in units of K assuming backside surface is a black body?
a. 315
b. 287
c. 378
d. None of the above
