... question that is raised herein is about the flow regime in the vent pipe. The investigation of flow regimes in oil pipes was recently carried out in the ATOS program ( 4 ) and the method was applied here as well. For the vent pipe flow the Hewitt and Roberts ( 8 ) charts were used whereas for the scavenge...
