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 CPA < CPB KA>2 kB CPA > CPB KA < 0.5kB CPA < CPB KA>2 kB CPA > CPB KA < 0.5kB ANSWER DOWNLOAD EXAMIANS APP

Heat Transfer A long iron rod initially at a temperature of 20°C has one end dipped in boiling water (100°C) at time, t = 0. The curved surface of the rod is insulated so that heat conduction is one dimensional in the axial direction. The temperature at a distance 100 mm from the dipped end becomes 40°C at time, t = 200 s. The same temperature is achieved at a distance of 200 mm from the dipped end at time t = 283 s t = 356 s t = 400 s t = 800 s t = 283 s t = 356 s t = 400 s t = 800 s ANSWER DOWNLOAD EXAMIANS APP
