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 < 0.5kB CPA > CPB KA>2 kB CPA < CPB KA < 0.5kB CPA > CPB KA>2 kB CPA < CPB ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For a liquid in laminar flow through a very long tube, when the exit fluid temperature approaches the wall temperature, the equation to be used is Nu = Gz Nu = 0.023 Re0.8 . Pr0.4 Nu = 2Gz0.5 Nu = Gz Nu = Gz Nu = 0.023 Re0.8 . Pr0.4 Nu = 2Gz0.5 Nu = Gz ANSWER DOWNLOAD EXAMIANS APP
