Heat Transfer Condensing film co-efficient for steam on horizontal tubes ranges from 5000 to 15000 Kcal/hr.m² .°C. Condensation of vapor is carried out inside the tube in a shell and tube heat exchanger, when the Temperature of the incoming vapor is very high Higher condensing film co-efficient is desired Lower pressure drop through the exchanger is desired Condensate is corrosive in nature Temperature of the incoming vapor is very high Higher condensing film co-efficient is desired Lower pressure drop through the exchanger is desired Condensate is corrosive in nature ANSWER DOWNLOAD EXAMIANS APP
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 d²T/dZ² > 0 dT/dZ = 0 d²T/dZ² = 0 d²T/dZ² < 0 d²T/dZ² > 0 dT/dZ = 0 ANSWER DOWNLOAD EXAMIANS APP
