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

Heat Transfer The Sieder-Tate correlation for heat transfer in turbulent flow in pipe gives Nu α Re0.8, where, Nu is the Nusselt number and Re is the Reynolds number for the flow. Assuming that this relation is valid, the heat transfer co-efficient varies with the pipe diameter (D) as (D)-1.8 (D)-0.2 (D)1.8 (D)0.2 (D)-1.8 (D)-0.2 (D)1.8 (D)0.2 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the Low pressure drop High heat transfer co-efficient Flexibility possible in the baffle arrangement Less corrosion problems Low pressure drop High heat transfer co-efficient Flexibility possible in the baffle arrangement Less corrosion problems ANSWER DOWNLOAD EXAMIANS APP
