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>2 kB KA < 0.5kB CPA < CPB CPA > CPB KA>2 kB KA < 0.5kB CPA < CPB CPA > CPB ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Flows outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Can flow either inside or outside the tubes Flows outside the tubes Should not be used as it gives very high pressure drop Flows through the tube Can flow either inside or outside the tubes ANSWER DOWNLOAD EXAMIANS APP
