Using a tracer method, we investigate transfers in idealised systems comprising a diffusive solid pervaded by an array of channels through which a liquid flows according to a Hagen-Poiseuille velocity field. We systematically measure the transfer efficiency for systems of differing average flow velocity, diffusivity, channel radius, length and spacing. We present a semi-empirical model that relates transfer efficiency to the system variables. The model captures the entire range of results. From this model, we derive a transfer efficiency chart to serve as a starting point for the design of engineered biological systems.
