We use molecular dynamics simulations to show that the Venturi–Bernoulli effect can pump liquids at the nanoscale. In particular, we found that water flowing in an open reservoir close to a static substrate experiences a friction which converts its kinetic energy into breaking of hydrogen bonds. This water flowing under friction acquires a lower density, which can be used in pumping fluids positioned under a nanoporous substrate.
