Heat Transfer A composite wall consists of two plates A and B placed in series normal to the flow of heat. The thermal conductivities are kA and kB and the specific heat capacities are CPA and CPB for plates A and B respectively. Plate B has twice the thickness of plate A. At steady state, the temperature difference across plate A is greater than that across plate B, when KA < 0.5kB CPA > CPB CPA < CPB KA>2 kB KA < 0.5kB CPA > CPB CPA < CPB KA>2 kB ANSWER DOWNLOAD EXAMIANS APP
