Question

kindly answer this mass transfer problem  on mass transfer coefficient

Mass Transfer Coefficient A wastewater stream is introduced to the top of a mass- transfer tower where it flows countercurrent to an air stream. At one point in the tower, the wastewater stream contains 10-³ mole A/m³ and the air is essentially free of any A. At the operation conditions within the tower, the film mass-transfer coefficients are K₁ = 5x10-4 kmol/m².s.(kmol/m³) and KG = 0.01 kmol/m².s.atm. The concentrations are in the Henry's law region where PA,i = HCA,i with H =10 atm/(kmol/m³). Determine the following: (a) The overall mass flux of A (b) The overall mass-transfer coefficients, KoL and KOG.
