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 dT/dZ = 0 d²T/dZ² < 0 d²T/dZ² > 0 d²T/dZ² = 0 dT/dZ = 0 d²T/dZ² < 0 d²T/dZ² > 0 d²T/dZ² = 0 ANSWER DOWNLOAD EXAMIANS APP
