Heat Transfer In regenerative air preheater (as practised in heating of coke ovens), the heat is transferred Through a metallic wall By direct contact of hot flue gas with air By heating an intermediate material (like chequor bricks) and then heating the air from this hot material None of these Through a metallic wall By direct contact of hot flue gas with air By heating an intermediate material (like chequor bricks) and then heating the air from this hot material None of these ANSWER DOWNLOAD EXAMIANS APP
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
