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 In a shell and tube heat exchanger, The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The relationship is not generalised ANSWER DOWNLOAD EXAMIANS APP
