A droplet of liquid A, of radius r1, is suspended in a stream of gas B. It is believed that there is a spherical stagnant gas film of radius r2 surrounding the droplet. The concentration of A in the gas phase is xA1 at r = r1 and xA2 at the outer edge of the film, r = r2. Determine a relationship for the flux, NA,r at r = r1. b) What is the limit of this expression when r2 goes to infinity?
