Heat Transfer The advantage of backward feed multiple effect evaporators over forward feed units is that Heat sensitive material can be handled Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature There is no additional cost of pumping Heat sensitive material can be handled Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature There is no additional cost of pumping 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 6.1 1.74 1 37 6.1 1.74 1 37 ANSWER DOWNLOAD EXAMIANS APP
