Heat Transfer For a counter current heat exchanger with Tih = 80°C, T°c = 60°C, T°h = 50°C and Tic = 30°C, and the temperature difference between the two streams being the same everywhere along Z, the direction of flow of hot fluid. The temperature profile should satisfy d²T/dZ² < 0 d²T/dZ² > 0 dT/dZ = 0 d²T/dZ² = 0 d²T/dZ² < 0 d²T/dZ² > 0 dT/dZ = 0 d²T/dZ² = 0 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 KA < 0.5kB KA>2 kB CPA < CPB CPA > CPB KA < 0.5kB KA>2 kB CPA < CPB CPA > CPB ANSWER DOWNLOAD EXAMIANS APP
