An industrial wall is constructed of 20 cm thick fireclay of thermal conductivity 1W/m 0C. This is covered on the outer surface with a 3 cm layer of insulating material of thermal conductivity 0.075 W/m0C. The innermost surface is at 940 0C and the outermost surface is at 40 0C . The steady state of heat transfer is occurring through the wall. So what is the rate of heat transfer rate that is occurring through the wall? What is the temp of the interface of these walls?

Q2: A 2.5 -mm-diameter electrical wire is insulated by a 2-mm-thick rubberized sheath (* = 0.11 W/m K), and the wire/sheath interface. The convection heat transfer coefficient of the outer surface of the sheath is 10 W/m² K, and the temperature of the ambient air is 20 C. If the temperature of the insulation may not exceed 50 C, what is the maximum allowable electrical power that may be dissipated per unit length of the conductor?
