Repeat the Problem 1.31 including a contact resistance of 0.1 K/W at each of the interfaces. Problem 1.31: A section of a composite wall with the dimensions shown in the schematic diagram below has uniform temperatures of 200C and 50C over the left and right surfaces, respectively. If the thermal conductivities of the wall materials are: kA = 70 W/(m K), kB = 60 W/(m K), kC = 40 W/(m K), and kD = 20 W/(m K), determine the rate of heat transfer through this section of the wall and the temperatures at the interfaces.GIVENComposite wallThermal conductivities:kA = 70 W/(mK)kB = 60 W/(mK)kC = 40 W/(mK)kD = 20W/(mK)Surface temperaturesLeft side (TAs) = 200CRight side (TDs) = 50CContact resistance at each interface (Ri) = 0.1 K/WASSUMPTIONSOne dimensional conductionThe system is in steadystate
