Convection is faster than conduction?
In a wetted-wall tower, an air-H<sub>2</sub>S mixture is flowing by a film of water which is flowing as a thin film down a vertical plate. The H<sub>2</sub>S is being absorbed from the air to the water at a total pressure of 1.50 atm abs and 30<sup>o</sup>C. The value of k<sub>c</sub> of 9.567 10<sup>-4</sup> m/s has been predicted for the gas-phase mass-transfer coefficient. At a given point the mole fraction of H<sub>2</sub>S in the liquid at the liquid-gas interface is 2.0 10<sup>-5</sup> and p<sub>A</sub> of H<sub>2</sub>S in the gas is 0.05 atm. The Henry s law equilibrium relation is p<sub>A</sub>(atm) = 609x<sub>A</sub> (mole fraction in liquid). Calculate the rate of absorption of H<sub>2</sub>S.
