Heat Transfer Air is to be heated by condensing steam. Two heat exchangers are available (i) a shell and tube heat exchanger and (ii) a finned tube heat exchanger. Tube side heat transfer area are equal in both the cases. The recommended arrangement is Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air inside tubes and steam on shell side Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air inside tubes and steam on shell side 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
