A multiscale analysis is carried out for the pressure driven flow rate through a micro/nano slit pore when the adsorbed layer-fluid interfacial slippage is considered. The flow of the adsorbed layer on the channel wall is described by the flow factor approach model for nanoscale flow, and the flow of the continuum fluid intermediate between the two adsorbed layers is described by a continuum fluid model. The adsorbed layer-fluid interfacial slippage is considered, while the adsorbed layer-wall surface interfacial slippage is ignored. The weak, medium-level and strong fluid-wall interactions and the solid adsorbed layer assumption are respectively taken. It is shown that when the thickness of the adsorbed layer is far lower than the continuum fluid film thickness, the adsorbed layer can be treated as a solid layer in spite of the fluid-wall interaction, otherwise the fluid-wall interaction has a significant influence on the critical power loss on the channel for motivating the interfacial slippage and on the total volume flow rate through the channel before the occurrence of the interfacial slippage; However, when the adsorbed layer-fluid interfacial slippage occurs, the fluid-wall interaction has a negligible influence on the normalized total volume flow rate through the channel vs. power loss on the channel curve and when using this curve for calculating the dimensionless volume flow rate through the channel the adsorbed layer can be taken as a solid layer. In general, only when the fluid-wall interaction is strong, the adsorbed layer can be taken as a solid layer in simulating the channel flow.
