Results of experimental investigations of the influence of the separation of the air dissolved in a fuel on the regime of flow of this fuel in a pipeline at an underpressure are presented. It is shown that, when the pressure in the pipeline decreases, beginning with any its value, the flow rate of the fuel in the pipeline decreases sharply as a result of the separation of air from it and the formation of the two-phase fuel-air flow. It has been established that the pressure at which active separation of the air dissolved in the fuel begins depends on the temperature of the fuel and the velocity of its flow in the pipeline. © 2013 Springer Science+Business Media New York.
