If the separation and reflux ratio remains unchanged, the number of ideal stages will Increase Decrease Depend on saturated boiling point; may increase or decrease Remains same Increase Decrease Depend on saturated boiling point; may increase or decrease Remains same ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The individual mass transfer co-efficients (moles/m² . s) for absorption of a solute from a gas mixture into a liquid solvent are, KL = 4.5 and KG = 1.5. The slope of the equilibrium line is 3. Which of the following resistance (s) is (are) controlling ? Gas side Interfacial Both liquid and gas side Liquid side Gas side Interfacial Both liquid and gas side Liquid side ANSWER DOWNLOAD EXAMIANS APP
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 partially mis-cible liquids The system comprises of miscible 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 partially mis-cible liquids The system comprises of miscible 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
