Mass Transfer If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that The system comprises of miscible liquids The system comprises of partially mis-cible liquids On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of an azeotrope The system comprises of miscible liquids The system comprises of partially mis-cible liquids On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of an azeotrope ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer A 25 cm x 25 cm x 1 cm flat sheet weighing 1.2 kg initially was dried from both sides under constant drying rate conditions. It took 1500 seconds for the weight of the sheet to reduce to 1.05 kg. Another 1m x 1m x 1cm flat sheet of the same material is to be dried from one side only.Under the same constant drying rate conditions, the time required for drying (in seconds) from its initial weight of 19.2 kg to 17.6 kg is 2500 2000 1000 1500 2500 2000 1000 1500 ANSWER DOWNLOAD EXAMIANS APP
