4. At a flow rate of 0.50 m/s Re = 50 for aqueous phases in a 100-μm-wide channel. The broadening of a liquid-liquid interface by diffusion is given by 〈 x diff 2 〉 = 2 Dt diff with diffusion coefficient D (cm 2 /s) and x diff (cm) and t diff (s) the distance and time of diffusion respectively [P. W. Atkins Physical Chemistry (Freeman New York 1994)]. The broadening of the features fabricated by FLO cannot be calculated with that equation alone because the profile of pressure-driven flow is parabolic [
