Heat Transfer The advantage of backward feed multiple effect evaporators over forward feed units is that There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature Heat sensitive material can be handled There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature Heat sensitive material can be handled 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 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 Temperature of the incoming vapor is very high Higher condensing film co-efficient is desired ANSWER DOWNLOAD EXAMIANS APP
