Hello For my study i'm making a specific design I'm trying to design a ballast chamber which i want to empty with a venturi pump I attached a schematic image of the idea Through pipe A a liquid is pumped with around 150m3/h through a 6'' pipe. The pipe is narrowed at the end, with a space between the narrowed part en the underside of the chamber. The idea is that the liquid from chamber '2' will be pulledbecause of the flow from 'A' trough the narrowing to 'C'. The whole chamber is located 2 meters under water level, so there will be a water pressure from underneath. There is an air hose that will add air to chamber '2' so it won't create a vacuum My question is: Does this idea even work (under water) and how can i calculate the sizes and volumes that will be pumped away from chamber '2' Thank you in advance!
