In this investigation an adaptive-network-based fuzzy inference system ANFIS is presented to solve this problem. The proposed ANFIS approach can construct an inputoutput mapping based on both human knowledge in the form of fuzzy if-then rules and stipulated input-output data pairs. Good performance of the designed ANFIS ensures its capability as a promising tool for modeling and prediction of fluid flow at nanoscale where the continuum models of fluid dynamics tend to break down. Keywords Carbon nanotube Water diffusion Artificial intelligence Modeling and prediction Introduction Carbon nanotubes CNTs have drawn much attention not only for their exceptional mechanical and electrical properties but also for their application in the new emerging area of nanofluidics since they can transport fluids at an extraordinarily fast flow rate. This property has diverse applications such as in charge storage devices 1 membrane industry 2 drug-delivery devices 3 and understanding the transport processes in biological channels 4 . In the past few years a significant number of works have been devoted to the study of fluid flow through CNTs S. Ahadian El Y.

Fast pressure-driven flow of fluids in membranes of CNTs 1.6 and 7 nm in diameter has been measured by Majumder et al. 5 and Holt et al. 6 respectively. They indicated measured values of 2 to 5 orders of magnitude larger than those calculated by the continuum-based no-slip
