## Abstract

A nonlinear kinetic exclusion model is used to study osmosis and pressure driven flows through nearly single file pores such as antibiotic channels, aquaporins, zeolites and nanotubules. Two possible maxima in the steady state flux as a function of pore-solvent affinity are found. For small driving forces, the linear macroscopic osmotic and hydraulic permeabilities $P\_{os}$ and $L\_{p}$, are defined in terms of microscopic kinetic parameters. The dependences of the flux on activation energies, pore length and radius, and driving forces are explored and Arrhenius temperature dependences derived. Reasonable values for the physical parameters used in the analyses yield transport rates consistent with experimental measurements. Experimental consequences and interpretations are examined, and a straightforward extension to osmosis through disordered pores is given.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
