Indicator Dispersal by Convection and Diffusion in Fluid Flow Through a Tube
A tube is filled with water containing indicator and then the indicator is washed out by laminar flow of indicator-free water. Given a measurement of mean volume concentration of indicator in the effluent as a function of time, a theoretical expression is derived for the pattern of indicator delivery in the case where diffusion is superimposed on convective transport. Satisfactory experimental verification of the theoretical expressions was obtained.
