Abstract
A pressurized fluid transfer system is provided comprising a supply storage vessel, a receiver storage vessel, a fluid flow passage extending from the supply storage vessel to the receiver storage vessel, a sonic nozzle comprising a convergent nozzle portion, a divergent nozzle portion, and a nozzle throat positioned between the convergent nozzle portion and the divergent nozzle portion. The nozzle throat defines a minimum flow area orifice having a cross sectional flow area which is smaller than a remainder of flow orifices within the system. Further, a sonic nozzle is provided in a pressurized fluid storage system such that sonic fluid flow into the fluid storage vessel is maintained until the storage vessel is about 90-95% full.
