Heat Transfer The advantage of backward feed multiple effect evaporators over forward feed units is that Most concentrated liquid is at highest temperature There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Heat sensitive material can be handled Most concentrated liquid is at highest temperature There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Heat sensitive material can be handled ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In regenerative air preheater (as practised in heating of coke ovens), the heat is transferred Through a metallic wall By heating an intermediate material (like chequor bricks) and then heating the air from this hot material By direct contact of hot flue gas with air None of these Through a metallic wall By heating an intermediate material (like chequor bricks) and then heating the air from this hot material By direct contact of hot flue gas with air None of these ANSWER DOWNLOAD EXAMIANS APP
