    • The comparison of the two terms in equation (29) requires several individual estimations: A) The pressure gradient is approximated by the one in a Poiseuille flow in the same rectangular channel. This should be a good approximation for a dilute solution at the entrance of the channel near the reservoir. We take typical values from reference [7, namely v 0 (L, 13 μm/s, w, 200 μm, h, 20 μm, together with the viscosity of water, η, 10-3kg/(ms, This leaves us with a pressure gradient of ΔP/L, η α(w/h) v0/wh ≈ 3.9 Pa/m, 93) with the shape-factor α(100) ≈ 1200 taken from reference [19, As a further approximation B) we take the chemical potentials in their dilute limit, where γS becomes logarithmic in cs, yielding ∂(γ s, γw)/∂cs ≈ kT, m
