Flow through an annular orifice
WebJul 13, 2004 · Two issues. Irregular orifices can be dealt with on the basis of an hydraulic radius (i.e. an effective flow area) regardless of the shape. This is approximate. As far as the flow through your 0.7" slot, you know the area and you either know the pressure drop or you can estimate the fluid velocity. Either way you can come up with a flow estimate. WebOct 3, 2024 · Because we know the inner diameter of the annulus (the pintle body OD), and the properties of the liquid flowing through the reservoir leading to the injector orifice, we were able to calculate an …
