![Required information
Consider the base plate of a(n) 770-W household iron with a thickness of L = 0.6 cm, base area of A = 160 cm4, and
thermal conductivity of k= 60 W/m K. The inner surface of the base plate is subjected to uniform heat flux generated by
the resistance heaters inside. When steady operating conditions are reached, the outer surface temperature of the plate is
measured to be 112°C.
