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 liquid in laminar flow through a very long tube, when the exit fluid temperature approaches the wall temperature, the equation to be used is Nu = 0.023 Re0.8 . Pr0.4 Nu = 2Gz0.5 Nu = Gz Nu = Gz Nu = 0.023 Re0.8 . Pr0.4 Nu = 2Gz0.5 Nu = Gz Nu = Gz ANSWER DOWNLOAD EXAMIANS APP
