Flow through an annular orifice
WebDec 23, 2024 · The development length of the annular flow downstream of the orifice is evaluated based on the integral volume fraction and the change of the film … 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.

Webdetermine the mass flow rate in the annular passage. At the outer tube wall, the stream function value is specified as zero (~O o = 0). At the inner tube wall, the stream function value is I]/i ~--- (1 - r2)/2 (4) which corresponds to the volume flow rate in an annulus with WebFlow through a Sharp-edged Orifice. Consider an orifice plate placed in a pipe flow as shown in Fig. 3.25 . We assume that the thickness of the plate is small in comparison to the pipe diameter. Let the orifice be sharp …
WebThe coarse filter may be located on either the upstream side or the downstream side of the metering orifice and in one embodiment of the invention the coarse filter is adapted to move away from the metering orifice under predetermined pressure so that fluid flowing through the metering orifice will by-pass the coarse filter. 权利要求 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.
