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 dT/dZ = 0 d²T/dZ² < 0 d²T/dZ² = 0 d²T/dZ² > 0 dT/dZ = 0 d²T/dZ² < 0 d²T/dZ² = 0 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Indirect contact heat exchangers are preferred over direct contact heat exchangers, because There is no mist formation Cost of equipment is lower There is no risk of contamination Heat transfer co-efficient are high There is no mist formation Cost of equipment is lower There is no risk of contamination Heat transfer co-efficient are high ANSWER DOWNLOAD EXAMIANS APP
