Heat Transfer The Sieder-Tate correlation for heat transfer in turbulent flow in pipe gives Nu α Re0.8, where, Nu is the Nusselt number and Re is the Reynolds number for the flow. Assuming that this relation is valid, the heat transfer co-efficient varies with the pipe diameter (D) as (D)0.2 (D)-0.2 (D)-1.8 (D)1.8 (D)0.2 (D)-0.2 (D)-1.8 (D)1.8 ANSWER DOWNLOAD EXAMIANS APP
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 Higher condensing film co-efficient is desired Temperature of the incoming vapor is very high Lower pressure drop through the exchanger is desired Condensate is corrosive in nature Higher condensing film co-efficient is desired Temperature of the incoming vapor is very high 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
