© 2020 Published under licence by IOP Publishing Ltd.It is known that for the most nanoporous medium-non-wetting liquid systems are observed non-outflow phenomenon. It is shown that this phenomenon may depend on many factors, one of which is a waiting time. The observed anomalously slow relaxation (non-wetting liquid outflow) caused by formation of strongly interacting states of liquid clusters in pores. Previously was shown that relaxation of such states can occur due to relaxation of metastable local configurations of filled and empty pores. In the present work the relaxation of non-wetting liquid (water) dispersed in disordered nanoporous medium (hydrophobic silica gel Libersorb 23) for 6 and 9° C is considered. The pore size distribution functions of captured liquid for 9° C are obtained. Some local configurations for 6 and 9° C are analyzed and their lifetimes are defined.
