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 Condensate is corrosive in nature Lower pressure drop through the exchanger is desired Temperature of the incoming vapor is very high Higher condensing film co-efficient is desired Condensate is corrosive in nature Lower pressure drop through the exchanger is desired Temperature of the incoming vapor is very high Higher condensing film co-efficient is desired ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In case of parallel flow heat exchanger, the lowest temperature theoretically attainable by the hot fluid is __________ the outlet temperature of the cold fluid. More than Less than Equal to Either more or less than (depending upon the fluid) More than Less than Equal to Either more or less than (depending upon the fluid) ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For turbulent flow in a tube, the heat transfer co-efficient is obtained from the Dittus-Boelter correlation. If the tube diameter is halved and the flow rate is doubled, then the heat transfer co-efficient will change by a factor of 37 6.1 1.74 1 37 6.1 1.74 1 ANSWER DOWNLOAD EXAMIANS APP
