WebDec 5, 2024 · Vortex shedding is the process by which vortices of gas or liquid are formed around a solid object that obstructs the path of a gas or liquid stream. These “shed” vortices are carried downstream in the flow … WebAug 4, 2012 · The term rangeability R is used for the ratio Q max /Q min, i.e. the ratio of the maximum to minimum rates of controlled flow. Thus, if the minimum controllable flow is 2.0% of the maximum controllable flow, then the rangeability is 100/2.0=50. Valves are … Figure 16-1.
