Flow through an annular orifice

WebAlso, net radial force at the annular orifice increases with both inlet velocity and opening size. The paper presents results demonstrating that the net radial force from fluid flow through the orifice could increase friction resistance and cannot be safely ignored, especially under high-flow-rate conditions. WebThe flow rate of a known orifice is typed into the computer and timed as the water rises from the lower photocell to the higher photocell. The known flow rate multiplied by time gives a volume. In subsequent flow calibration tests this volume is divided by computer measured time and converted into a rated flow and orifice diameter. 2.
