Observation of fluid flow in a segmented self-siphon has been conducted experimentally and a model using molecular dynamics method is used to study the phenomenon in simulation. Influence of number of parts used in vertical straight segments observed in the simulation is nearly similar to the result observed in experiment. Mismatch error between experiment and simulation results, in predicting whether water can flow in a configuration of segmented a self-siphon or not, has been found about 10.4 %. During the flow through the self-siphon water velocity decreases, especially in the semi-circle bends.
