We previously presented results obtained for liquid flow of tap water flow in 530 to 50 μm-diameters microtubes and evidenced a clear deviation from the classical Stokes flow theory which predict a constant Poiseuille number of 64 [1]. We assumed that using the EDL theory and a constant ζ potential approach may explain our results [2]. To confirm the previous obtained results, we used our dedicated experimental set-up [3] to study other fluids: ionic (distilled water, KCl solutions) and nonionic (n-dodecane). Here, for distilled water and n-dodecane, the same range of microtubes diameters have been investigated. For KCl solutions, the experiments were realized at constant microtube diameter (152 μm) for 5 different solutions concentrations. For a given diameter, the experiments are performed using 4 microtubes’ lengths then to ensure an accurate calculation of the Poiseuille number. We evidence different behaviours for given experimental conditions (that is microtubes inner diameters and surface roughness) depending of the fluid ionic characteristics. Here, we mainly present new experimental.
