Awetted-wall absorption tower is fed with water as the wall liquid and an ammonia-air gas mixture as the central-core gas. at a particular level in the tower, the ammonia concentration in the bulk gas is 80 mol%, that in the bulk liquid 5 mol%. the temperature is 30 c and the pressure 1 atm. the local mass transfer in the liquid is kl = 2.87*10-5 m/s and in the gas is kc = 0.0362 m/s. calculate the local molar flux for the absorption of ammonia using the overall mass-transfer coefficient ky, ignoring the vaporization of water.

note: for this problem, use equilibrium data of nh3-water from appendix a.3-22 from the textbook.
