Determine an average diffusivity of H,S in water, using penetration theory, from the data below for absorption of H2S into a laminar jet of water at 20C. Jet diameter=1 cm, jet length=7 cm, and solubility of H2S in water is 100 mol/m. Assume the contact time is the time of exposure of the jet. Jet Flow Rate, cm /s Rate of Absorption, mol/s x 106 0.143 1.5 0.568 3.0 1.278 4.25 2.372 6.15 3.571 7.20 5.142 8.75
