The power loss is calculated by a multiscale approach in the pressure driven mass transfer in a micro slit pore where there are the physical adsorbed layers respectively on the coupled walls and intermediate between them is a continuum fluid flow. The flow factor approach model for nanoscale flow is taken to simulate the flow of the adsorbed layer, and conventional hydrodynamic flow theory models the continuum fluid flow. The calculation shows that the adsorbed layer on the wall surface can have a very significant effect on the power loss in this multiscale mass transfer, and it can greatly reduce the power loss on the channel owing to heavily reducing the flow rate through the channel because of the strong fluid-wall interaction. In the case of the interfacial slippage on both the wall surfaces, there is a critical power loss in the channel to generate the interfacial slippage, and the power loss on the channel is proportionally increased with the increase of the interfacial slipping velocity, which significantly enlarges the mass flow rate through the channel.
