Heat Transfer A backward feed multiple effect evaporator is better than forward feed for concentrating cold feed, because it provides Lower economy Lower capacity Both A & B Higher economy Lower economy Lower capacity Both A & B Higher economy ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A hollow sphere and a solid sphere of the same material and equal radii are heated to the same temperature. In this case, Both will absorb equal amount of radiation from the surrounding in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both the spheres will emit equal amount of radiation per unit time in the beginning Both B & C Both will absorb equal amount of radiation from the surrounding in the beginning The cooling rate will be the same for the two spheres and hence the two spheres will have equal temperatures at any instant Both the spheres will emit equal amount of radiation per unit time in the beginning Both B & C ANSWER DOWNLOAD EXAMIANS APP
