Heat Transfer Economy of a multiple effect evaporator is not influenced much by the rate of heat transfer ratio of the weight of the thin liquor to thick liquor temperature of the feed boiling point elevations rate of heat transfer ratio of the weight of the thin liquor to thick liquor temperature of the feed boiling point elevations ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a shell and tube heat exchanger, The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances The relationship is not generalised There is no relationship between temperature drop and resistance The temperature drop is inversely proportional to the resistance across which the drop occurs ANSWER DOWNLOAD EXAMIANS APP
