WebNov 1, 2024 · BACKGROUND AND PURPOSE: Flow diversion has gradually become a standard treatment for intracranial aneurysms of the anterior circulation. Recently, the off-label use of the flow diverters to treat posterior circulation aneurysms has also increased despite initial concerns of rupture and the suboptimal results. This study aimed to explore … The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: … See more The metric equivalent flow factor (Kv) is calculated using metric units : where Kv is the flow factor (expressed in m ·h ). Q is the flowrate (expressed in cubic metres per hour m … See more • Discharge coefficient See more
