Consider a system in which component A is being transferred from a gas phase to a liquid phase. The equilibrium relation is given by ya = 0.75-A where ya and IA are mole fractions of A in gas and liquid phase respectively. At one point in the equipment, the gas contains 10 mole % A and liquid 2 mole % A. Gas film mass transfer coefficient k, at this point is 10 kmol/(hr.m².Aya) and 60% of the resistance is in the gas film. Calculate: (a) the overall mass transfer coefficient in kmol/(hr.m².Aya). (b) mass flux of A in kmol/(hr.m²). (c) the interfacial gas concentration of A in mole fraction.

Consider a system in which component A is being transferred from & gas phase to a liquid phase. The equilibrium relation is given by ya = 0.75za where ya and 1A are mole fractions of A in gas and liquid phase respectively. At one point in the equipment, the gas contains 10 mole % A and liquid 2 mole % A. Gas film mass transfer coefficient ky at this point is 10 kmol/(hr.m².Aya) and 60% of the resistance is in the gas film. Calculate: (a) the overall mass transfer coefficient in kmol/(hr.m².Aya). (b) mass flux of A in kmol/(hr.m²). (c) the interfacial gas concentration of A in mole fraction.
