In the circular cross section, open top mouth and truncated cone shaped tube shown in the figure, liquid A evaporates and passes into the A+B gas mixture flowing out of the tube. Gas concentration A on the outside of the tube is given as CA1. It is accepted that 1-dimensional and steady state conditions prevail. The radius at the conical cabin, liquid gas interface is ro, and the radius at the open mouth is r1. a. Explain how to write the limit condition at the liquid-gas interface. b. Obtain the expression for the density distribution of gas A in the tube. C. Obtain the expression for the evaporation rate of liquid A
