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 Condensate is corrosive in nature Higher condensing film co-efficient is desired Lower pressure drop through the exchanger is desired Temperature of the incoming vapor is very high Condensate is corrosive in nature Higher condensing film co-efficient is desired Lower pressure drop through the exchanger is desired ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A steel sphere of radius 0.1 m at 400°K is immersed in an oil at 300°K. If the centre of the sphere reaches 350°K in 20 minutes, how long will it take for a 0.05 m radius steel sphere to reach the same temperature (at the centre) under identical conditions ? Assume that the conductive heat transfer co-efficient is infinitely large. 20 minutes 5 minutes 40 minutes 10 minutes 20 minutes 5 minutes 40 minutes 10 minutes ANSWER DOWNLOAD EXAMIANS APP
